Gideon Walker was married to Cheif Walkers Grandaughter.
His first wife was a Cogswell and they went to Virginia as they were friends of George Washington and Andrew Jackson.
They were also related to Daniel Boone. Here is what I found.

Conn. Born 15 Jun 1751 in Springfield, Conn. Died 15 Nov 1830 in Kingston, Tenn. He enlisted in the American Revolution, serving as a Corporal in Captain Couch's Company of Col. Andrew Ward's regiment. Another record states that he also served in Captain Burt's Company at West Springfield, Mass.

Mr. and Mrs. Morgan remained in Connecticut until 1784, and then removed to Saratoga, New York before 1788. He was a surveyor, civil engineer, land speculator, and businessman. He laid out the town of Saratoga, N.Y. It is said that General Washington was a guest in their home the night of the birth of their son, who they named George Washington Morgan in the General's honor. Their next move was to Staunton, Virginia, where Patience Cogswell is believed to have died after giving birth to their last two children. He laid out the city of Staunton, Va., as well. He sold tracts of land in Morgantown, Albemarle Co., Va., and in New Haven, Rockingham Co., Va. See: The Allen Papers, McClung Collection, Lawson McGhee Library, Nashville.
He later remarried and removed to Kingston, Tenn., where he was given a permit by Gov. Blount to operate a tavern in Kingston. It is said that Sam Houston recovered from an arrow wound here, and that Andrew Jackson was a frequent visitor.
Cecil Holland wrote of Gideon Morgan: "The great grandfather of the raider [Gen. John Hunt Morgan], patriarch of the Morgan clan, and a relative of Gen. Daniel Morgan of the Revolution."
