I am not researching these people, just entering information from the booklet "Historical Atlas of Westmoreland County, Virginia" by David Eaton, 1942:
"John Mottram was in the House of Burgesses for Northumberland County in 1652.
"John Mottram patented 963 acres of land on King Copisco and Cabin Points.This was afterwards increased by Richard Wright to 2,200 acres.Richard Wright married Anne Mottram. to whom her father had willed the land.Their son, Major Francis Wright, married Ann Washington, only daughter of John Washington, the Emigrant.She inherited a large tract of land patented by her father near Index, now King George County."
"Col. John Mottram was a prime owner for the formation of the county of Northumberland its first representative in the House of Burgesses of Virginia.The numerous references to John Mottram Gentl. in the Northumberland and Westmoreland records prove that he was a young man of a very marked executive ability.He became involved in over thirty law suits within a short time, and in no case failed to win the judgment he sought.In 1661, with his brother-in-law, Col. Nicholas Spencer, (Frances, the daughter of John Mottram, married Nicholas Spencer) he obtained a patent to eleven hundred acres at Pascattaway on the Potomac, a part of which later was acquired by the Washingtons, embracing the site of the present Mount Vernon."
"In 1658 he secured a patent to 2,200 acres upon the Potomac between lower Machodoc River and Nomini Bay, upon which his son-in-law, Francis Wright settled."
