i am sure u have seen the williams at latrobe cemeterys. wm sr death cert signed by his son, who did not know who his grandfather was. but if wm sr knew, it should be on his marriage records. that may be why his birth place is given as dublin, ireland, his son was guessing, or knew that the family was from there.
