Thomas Cox baptism on 24 Mar 1673 (born 24 Mar 1673) in Boston, Suffolk, Massachusetts Bay, British Colonial America.
Could he be the Thomas Cox, widower from Boston, who married Johanna Haldron, also a widow, in the city of New York in September 1720? See her profile for more information. (Note: When New York Dutch church marriage records of that era said a person was "from" a place, it normally was their place of birth.)
