Nice to know you are still interested in the Girton line.I think about the last I heard from you was when you were exploring the Shubman name (how many years ago?).Are you completely retired now?
I have come across a few records with the Gurden spelling that proved to be our family. Guess I just have to accept the German origin.(I do accept it; just hard for an "old dog to learn new tricks".)
I posted my message in the hope of finding someone to whom my work might be helpful (with the understanding that it could not be used as the final word). Nowadays my only "research" is online; it keeps me busy looking, since so much is being posted daily.There are roughly 6000 individuals in my file carrying the Girton name, related and unrelated; about 10,000 descendants of our Thomas.
If you would like a gedcom or FTM file (FTM 2010; can't go backwards), just send me your snail mail address.
