As usual GenForum is making it nearly impossible to respond so I tried to change my e-mail address because the one shown here is no longer operating, but the master brain in charge of GenForum won't let me do it so here is my e-mail address for faster communication email@example.com.
I was able to trace your line using the book "George Genealogy" by Keith H. George. It's about 800 pages of deailed information on four main George lines: James George of Amesbury, Massachusetts / John George of Haverhill Massachusetts / Nicholas George of Dorchester, Massachusetts / Isaac George of Albany, New Hampshire. I don't know if the book is still available. It WAS available through the author's daughter a few years ago, but at that time she had only four or five copies left. If you go to Message #1504 on this forum it gives the address of the author's daughter.
The book has birth, marriage, and death dates with places. It lists all children and usually gives the names of the parents of George spouses. I looked up Catherine Clark and in this rare case it didn't name her parents only her birth and death dates and places. If you need dates and details let me know and I'd be happy to help, but not on GenForum because I'm sure the copyright on the book would allow me to share information "privately" but not here in a "public" forum.
