Thomas arrived in the colonies 1635 on the ship Thomas and John. The ship "Thomas and John" was owned by Thomas and John Culpeper, the sons of John Culpeper of Salehurst, Kent, England.

Marriages & Children
Thomas married only once. His wife's given name was Mary, as she is named in his will. There is some dispute about his wife. Most sources located state she is Mary Neal, daughter of Capt. John Neal. (See attached photo on this profile.) Some family trees state she was Mary Harrington, based (it appears) solely on the fact that one land grant for Thomas Bell adjoined that of Edward Harrington. I am inclined to the opinion that her name was Mary Neal. Further research is needed to confirm this.
