The Colonel's brother Robert followed a safer course. He prefixed the
"Mac" to his name; settled in Edinburgh; adopted the law as a
profession, and became a Writer to the Signet. He had a family of three
daughters, Catherine, Robina, and Mary Anne; and two sons, Andrew and
John.

John, the younger of Robert MacMurray's sons, was born at Edinburgh in
1745. After receiving a good general education, he entered the Royal
Marines under the special patronage of Sir George Yonge, Bart.,
[Footnote: Sir George Yonge was Governor of the Cape of Good Hope, and
subsequently Secretary at War; he died in 1812.] a well-known official
of the last century, and his commission as second lieutenant was dated
June 24, 1762. Peace was signed at the treaty of Paris in 1763, and
young MacMurray found himself quartered at Chatham, where the monotony
of the life to a young man of an active and energetic temperament became
almost intolerable. He determined therefore to retire on half-pay at the
age of twenty-three, and become a London bookseller!

It is not improbable that he was induced to embark on his proposed
enterprise by his recent marriage with Nancy Wemyss, daughter of Captain
Wemyss, then residing at Brompton, near Chatham.

While residing at Chatham, MacMurray renewed his acquaintance with
William Falconer, the poet, and author of "The Shipwreck," who, like
himself, was a native of Edinburgh.

To this friend, who was then on the eve of sailing to India, he wrote:

BROMPTON, KENT, _October_ 16, 1768.
