Nicoll was the father of the Signer, William. I have a date of 1857 (of birth/death/or marriage) for John G. Floyd, Sr., and there is a John G. Floyd Jr.
In 1777 General Floyd was in the Militia of Long Island. He was Appointed Senator of New York, and worked in the development of the new constitution and spoke in records of the Constitutional Conventions.As a Senator, there are documents about his part in the effort.
I believe his home was Mastic, Long Island, at the North Shore where a fire took part of the home..
1734-1821 for Nicoll Floyd. And, from Wales 1680 to Long Island. Part of a Book about the Declaration Signers gave me this much.
He was married twice, but there is no available information about his children in that quoted book. He held one term as Senator, and was not a part in the debate over the declaration. After that, held no other office, was ruined by the Revolution, and moved to Westernville in upstate NY. at age 69.
This is what I know.It is All I may know because I doubt that Captain John Floyd that was in Newberry SC was a part of any of that descendency.
