I do not have a ton of info on this family, but I do have documentation on James Lynes 1805 Maryland and children. Mostly on one of the children. I have no clue who is beyond James or his wife - Mary H. surname unknown. The signatures are Mary H Lynes.
I have a friend who is a Lyons and I think we are cousins!
Her family name ties into mine. It is wierd IMO
We really are one big family are we not? LOL
As far as the name change, Lyons is the correct way to spell it, but you know those census takers, and poor English spell-ers really do not take time to make sure they have information like spelling, down perfectly. They just write and get their job over with. scribble-scribble-scribble.
It must have been easier to allow the systems to keep their missed spelled words than face having to change the countless documentations needed to get all that done.
