When Matthew Colclough's son Robert died, his widow Susannah Griffith married a further two times. Firstly a man called Hillary. She then emigrated to Virginia with her 12 year old son John to Virginia, arriving on Dec 6th 1652. where she married ----Blagroe. Susan returned to England to bring over John's brother Ralph in 1655, leaving John with Griffith relations nearby. There were other Colcloughs in Virginia at the time; two were sons of George of Delph House and Elizabeth Keeling - John, a ship's captain who died unmarried and his brother George, who married twice but had no children, and Thomas the ship owner who was a son of George Colclough of Trentham and a great grandson of Matthew and Katherine Dalton. George Colclough of Westmoreland got into trouble when he persuaded Mottrom to do something concerning the inheritance of Mottrom's children. They were reported to be drinking all day before George persuaded Mottrom to make the change. When Mottrom, died George married his widow Ursula. A Richard Wright, who was the wife of one of Mottrom's daughters by his first wife, objected to the marriage. On George's death Ursula married for a fourth time the son of Jean Brewster and Isaac Allerton, who was an ancestor of Robert E Lee. His land in Lancaster Co. is now known as Sitchley
There is another John Colclough floating around, who arrives in Virginia in 1650. He might be the Susan's son, but if so he was very young to be doing the journey on his own. More research is needed
Between the York River and the Rappannock River is Colonial Gloucester County. On Chesapeake Bay, at the mouth of the Rappannock is Gwynn Island where Col Hugh Gwynn lived, who brought John Colclough as a headright in 1652. The lands on which John himself lived are now the Quantico Marine Base. Four years later Edward Prescott brought over one John Washington who settled nearby. By 1660 John was married to Mary Rivett or Partridge (whose sister was Alexander Doniphan's first wife Amy; their daughter was an ancestress of Col. Travis of The Alamo and of President Truman.) and he had three children, Benjamin, John and another son. John was a carpenter, as was his brother Benjamin, who constructed the barr in the county court house.
