The family traces its descent from the Barons of Dallas through
Sir William de Dolyes, Knight Lord of Dolj'es
(1289) and John de Dolas, cliief of his name and
first of Cantray (1442), down througli William
Dallas (1617), whose son, George Dallas, of Saint

lawyer and the author of the Scottish law book
known as St. Mar-
tin's Styles." He
was also keeper of
the privy seal of
Scotland during the
reign of James VII.
This seal afterward
came into the i)OS-
session of the fam-
ily of Lieut. -Gen.
Sir Thomas Dallas,
K.C.B. (1757), a
cousin of Alexander
James Dallas (1759),
who, as an ofTicer
in the British army,
distinguished him-
self in the Carnatic and later at the siege of Serin-
gapatam. Dr. Robert C. Dallas was a Scotch phy-
sician then practising on the island and soon
returned to Edinburgh, where, and at Westmin-
ster, his four sons were educated. Alexander read
law at the Temple in London, but the death of his
father, the great depreciation of his Jamaica
estates, and the marriage of his mother, deter-

remained two years. He then procured a com-
mission in the army. He was married, Sept. 4,
1780, to Arabella Maria, daughter of Maj. George
Smith of the British army and great-grand-
daughter of Sir Nicholas Trevanion, a wealthy
landowner in Cornwall. He then joined his
mother's family who had returned to Jamaica,
was appointed master in chancer^' and was
promised further advancement, but the con-
tinued illness of his wife determined him to take
£700, his portion of the patrimony, and find a
home in America. On June 8, 1783, he settled in
Philadelphia and took the oath of allegiance to
the commonwealth of Pennsylvania. He was
not then admitted to the bar on account of a law
reciuiring a two years" residence, and he became
clerk in the office of the commissioner for set-

master's departments in the Revolutionary army.
In July, 1785, he was admitted as an attorney
and counsellor in the supreme court of Penn.syl-

for Mr. Lewis Hallam, the theatrical manager,
and contributing to several literary perio<lical.s,
