I think I am related to the Alders you mention.My family tree goes back to 1370 (complete until around 1540)!
I have a George and Barbara (who was his sister) on the tree around 1639.George had two sons, another George and John.I'm related to the Georges, there were four generations called George.
We're all Freemen of Newcastle which is part of the rason the line has been traced.Someone did some research in the 1920s on the family and my Dad's cousin followed it up in the 1960s.I was made a freeman in 1989, only my second visit to Newcastle! I now live in London but was brought up in Yorkshire as a young child then Cape Town, South Africa.
My father still regards himself as a Geordie (navive of Newcastle) despite leaving in his late teens.
