quently the following lands were acquired by the family,
viz.-Isauld, in 1723, by Alexander Sinclair of Murkie,
filth Earl of Caithness; and Brubster and Brims in
1726-27, by his brother, Lord Murkie, to whom Alexander
succeeded, as heir of conquest.
James Sinclair, first of Murkie, married Elizabeth
Stewart, daughter of Robert, Earl of Strathearn and
Orkney, a natural son of King James V., and he had
two sons and a daughter-
1. James, his successor.
2. Francis, who served in the German wars, and who
is stated by Gordon to have held the rank of
serjeant-major. In 16211 he had returned to
Scotland, and married Janet, daughter of Alex-
ander Sutherland of Forse, by whom he had a
son, James, who left no issue. In a procuratory
of resignation of Murkle by Sir James Sinclair
in 1644, James Sinclair is mentioned as "eldest
lawful son" of Francis, his brother, and in the
Peerage case it was held that there was no
other son of Francis.
1. Agnes, who married John M'Kay of Dirlot and
Strathy.
James Sinclair had also a natural son, John Sinclair,
first of Assery.- Vide Assery.2
 
II. Sir James Sinclair, Knight, appears to have
been twice married. In January 1633 a disposition was
granted by him, with consent of Dame Margaret Dundas,
his spouse, of part of the lands of Ormlie; and in October
1634 there is a contract of marriage between him and
Jean, eldest daughter of William Stewart of Burray, who
is therein designed of "Manur." By Jean Stewart he
had two sons and five daughters:-
1. John, afterwards eighth Earl of Caithness.
2. David of Broynach, who died between 1713 and 1716.
David Sinclair of Broynach married a daughter of
William Sinclair of Dun, by whom he had a son, James,
and a daughter, Elizabeth.1 James died about 1754,
without issue. Elizabeth married James Whyte, in
Meikle Clyth, afterwards in Thurso, and had two
daughters, Henrietta and Jean. Henrietta Whyte
married William Miller, and. had a son, James, and a
daughter, Isabella, Jean Whyte married Donald Oagg,
weaver and merchant in Thurso, and had two sons,
James and Donald, and two daughters, Janet and Anne.
On the death of Lady Fife, only daughter of Alexander
Sinclair of Murkie, ninth Earl of Caithness, James and
Isabella Miller, and Donald and Anne Oagg, claimed and
obtained a share of her executry,2 as the great grand-
children of David of Broynach, Lady Fife's grand-uncle.
David of Broynach had also, by one Janet Ewen,3 or
2 Receipt, 26th September 1789.
3 By Janet Ewen, who was his ser-
Ewing, a son, David, who was reputed to be illegitimate
and on his death the Earl refused to permit him to be
buried in his burying-place. On the death of Earl
Alexander, James Sinclair, in Reiss, son of the reputed
illegitimate son, David, and grandson of David of Broy-
nach, claimed the title, on the allegation of his father's
legitimacy, in opposition to William Sinclair of Rattar.
In conjoined claims to be served heir before the Macers,
after proof by both parties, the jury, on 28th November
1768, pronounced a verdict by a majority in favour of
Rattar, which, after various proceedings before the
Court of Session, was confirmed. In 1786 James Sinclair
threatened to renew his claim to the title; but in 1788 he
died, and the question of his father's legitimacy became
unimportant, inasmuch as he had no issue, and no other
heir-male of his grandfather then remained alive.
1. Jean, the eldest daughter.1
2. Mary, who married, first, George Sinclair of Forss,
and, on his death, William Sutherland of
Geise.
3. Anne, "Mistress of Stemster," who married Alex-
ander Sinclair of Stemster, son of Alexander of
Latheron.
1 Disposition by her mother, 18th
May 1692.
4. Barbara, who married James Cunningham of
Reaster.
5. Katharine, who married Walter Innes of Skaill.
 
III. John Sinclair of Murkle succeeded to the
earldom of Caithness in 1698 as the eighth Earl, and
died in 1705. He married Jean Carmichael of the Hynd-
ford family, by whom he had four sons and a daughter:-
1. Alexander.
2. John, Lord Murkle, of the Court of Session, who
married Jean, daughter of the first Earl of Cro-
marty, and his wife, Anne, daughter of Sir James
Sinclair of Mey. He died in 1755 without issue.
3. Francis, who died without issue in 1762. In a
disposition in 1760 by him of the lands of
Milton of Lieurary and others, he settles the
lands on the "heirs-male of the marriage then
subsisting between him and Mrs. Janet Morrison."
4. Archibald, who also died without issue.1
1. Lady Janet, who married David Sinclair of South
Dun, by whom she had a daughter, Janet, who
married Stewart Threipland of Fingask, and
other children.
 
IV. Alexander Sinclair of Murkle, Ninth Earl
of Caithness, married Margaret, daughter of the first
Earl of Rosebery, by whom he had an only child-
Lady Dorothea, who married James, Earl of Fife, and
died without issue.
Earl Alexander had two natural sons, George Sinclair
in Geise, who died without issue, and Peter, who had a
son, James, who died without issue, and seven daughters,
of whom six married and had issue.
William Sinclair of Rattar was the lawful heir of
Earl Alexander on failure of his own family, they being
descended from two brothers, James Sinclair, first of
Murkie, and Sir John Sinclair, first of Greenland and
Rattar. But they do not seem to have been on friendly
terms, for in his correspondence with George Sinclair of
Woodhall, Lord of Session, in reference to a settlement
of his estates, Earl Alexander says: "Rattar is next
tho' very remote. Though he lives within four miles of
me he never comes to see me, from which it seems he is
disobliged because I did not give him all I had, and
depend for subsistence on his generosity. He cannot be
very wise, for he could not have taken a more effectual
way to disappoint his expectations."
Earl Alexander died in 1765. In 1761 he executed
an entail of the estate of Murkle and his other lands, by
which, on failure of his own heirs therein mentioned, the
property was disponed to Lord Woodhall and the heirs-
male of his body, and failing them to his, Lord Wood-
hall's, nearest lawful heirs-male of line; and under this
destination the succession was taken up on the Earl's
death by Sir John Sinclair of Stevenson, Lord Woodhall's
nephew. The Sinclairs of Stevenson are descended from
the Sinclairs of Longformacus, a branch of the family of
Roslyn. Sir Gregory Sinclair, third son of Sir William
of Roslyn, flourished in the reign of Robert the Bruce,
and the first Sinclair of Stevenson was George, second
son of Matthew, ninth Laird of Longformacus, who died
about 1620. His son, John, was a merchant in Edinburgh,
and was created a baronet, and purchased Stevenson and
other lands. He is now represented by Sir Robert
Charles Sinclair of Stevenson and Murkle, his lineal
descendant, and ninth baronet of Stevenson.
Janet Gordon, widow of James Sutherland of
Forse.
John Sinclair's second wife was Margaret Davidson,
who is traditionally supposed to have been of the David-
sons in Aehingills or Buckies, and by her he had-
1. John Sinclair, first of Lybster.
2. William, who, in 1670, held the wadset of Forsie,
and who was afterwards in Ulgrimbeg and Ulgri-
more. He married Jean, daughter of William
Sinclair of Dun, and had two daughters, Mary
and Elizabeth. The former married, in 1705,
Donald Gunn in Achalibster.
3. George, mentioned in 1652 and 1660.
1. Grizzel, who married John Doull, wadsetter of
Thuster, near Wick.- Vide Doulls.
2. Isabell, who married, first, Arthur Forbes, mer-
chant in Edinburgh, and, second, William Sinclair
of Dun.
3. Janet, who married, in 1616, George Munro,
Sheriff-Clerk of Caithness.
In a deed executed in 1665 by James, the eldest son
of John Sinclair, in which he reserves Margaret David-
son's liferent of Assery, she is designed "my mother,"
but she appears to have been only his stepmother, seeing
that John Sinclair of Lybster is mentioned as the eldest
son of the second marriage.
 
II. James Sinclair, Second of Assery, married
first, Elizabeth Balfour; and, second, Margaret, daughter
of David Munro, commissary of Caithness. He had
several sons and daughters:-
1. George, eldest son of his first marriage.
2. John, in Ulgrimbeg, married Bess Craigie. George
and John are named as brothers-german.
3. James, a merchant in Thurso, who died in 1713,
and had several sons, of whom Daniel was
minister of Longformacus. William was a mer-
chant in Thurso, and Alexander was a notary-
public in Thurso, and married Jean, daughter of
James Sinclair of Wester-Brims.
1. Katharine, eldest daughter, married Alexander
Gibson, Dean of Bower from 1668 to 1682.
 
III. George Sinclair, Third of Assery, was twice
married. His second wife was Isabel, daughter of
Patrick Sinclair of Ulbster. He had five sons and a
daughter:-
1. James, apparent in 1700.
2. John, called eldest lawful son in 1691.
3. Patrick.
4. George, eldest son of Isabel Sinclair.
5. Francis, also of the second marriage.
1. Elizabeth, the only daughter, married Richard
Sinclair of Thura.
The creditors of James, second of Assery, had led
apprisings against the estates, which were acquired by
Ulbster and Sir William Dunbar of Hempriggs. In 1675
Ulbster assigned his rights to John Sinclair (2); while,
in 1682, Sir William Dunbar conveyed his rights to
George Sinclair (4), then of Assery, and his sons, John
and Patrick.
 
IV. John Sinclair, Fourth of Assery, succeeded
his father, George, and in 1698 married Elizabeth Innes,
widow of Laurence Calder of Lynegar, by whom he had
an only son, John, his successor. He afterwards married
Barbara, daughter of Patrick Murray of Pennyland, by
whom he had an only child, Isabella, who married John
Sinclair of Scotscalder.
 
V. John Sinclair, Fifth of Assery, was served heir
in general to his father, John, in 1728, and in 1765 he was
infeft as eldest lawful son. He married Katharine, eldest
daughter of Robert Sinclair of Geise, and had-
1. Robert.
2. John.
3. Charles.
4. James.
1. Isabella, eldest daughter, who married Robert
Manson Sinclair of Bridgend.
2. Katharine.
3. Jean, who married Sir Benjamin Sinclair of Stem-
ster.
VI. Captain Robert Sinclair, Sixth of Assery,
was served heir to his father cum beneficio inventarii, in
1772. He married Katharine Sinclair, and had no issue.
The estate was brought to judicial sale by the
creditors, and Captain Sinclair having died during the
proceedings, they were continued against his brother,
John; and in 1784 Assery and Brawlbin were purchased
by Ulbster. The trustees of Sir John Sinclair sold the
lands to Mr. Campbell, merchant in London, and from
him they were purchased by the late James Sinclair of
Forss, for about £9000.
