I do not have any information on George before 1640. I have found that he arrived in Wethersfield, MA about 1640 (Wethersfield was, later, incorporated by CT). He moved to Springfield about 1646, where he married Hannah Haynes on 29 June 1648.
He had one child with Hannah, who they named Hester.
There is vague reference to 6 children arriving with him.
I know this isn't much help, but it is all I have on George.
