John Windsor, of Deal Island Marland, came to America in 1645, settled in Somerset Co. Maryland. Haplogroup R1b1a2. This means his ancestors originated in Iran and Iraq and came to Germany, Czechoslovakia, etc. about 10,000 years ago.
Jarvis Windsor, of Charles Co. Maryland, came to America in 1679. His haplogroup I1. This means these Windsors are not related at all to John Windsor of Deal Island, Maryland for at least 25,000 years. Haplogroup I1 settled in Norway, at the end of the last ice age, about 25,000 years ago. They were an isolated group and may be the group responsible for the mutations of blue eyes and blond hair.
We would like to get other Windsor/Winsor lines to test and see where the Windsor/Winsors came from.
We don't have any DNA results for descendants of these colonial lines:
Christopher Windsor of Fairfax Co. Virginia, came to America about 1716.
Joshua Winsor of Rhode Island, came to America in 1635.
Robert Winsor of Boston, Massachusetts came to America in 1635.
Samuel Winsor of Duxbury, Massachusetts, born in Boston, Massachusetts in 1725. DNA would show if he was indeed a descendant of Robert Windsor of Boston.
And all Windsor/Winsor lines, colonial or otherwise.
If you are a male with the surname Windsor, please consider having your DNA tested. It is relatively inexpensive (about $150) for a 37 marker test. There is an administrator for the Windsor DNA study if you wish to work with him, John Windsor, who has already posted on this web page his information.
