It's not hard to find gedcoms which "have" that Balthaser Bock's father was a Johannes Bock who settled into Berks County in Pre-Revolutionary War days.
Some of those include other siblings as well, but I've yet to find any that include any sisters for Balthaser.
This may simply be a moot question since there are no gedcoms to indicate that Balthaser's father left a will anyplace, but, does anyone know where that document might be located if one did exist?
Thanks!
