Peter Marks on the 1820 Census was in Huntingdon Co and appears on the census as: Huntingdon Co Franklin Twp 1820 Census males: 1 up to 10, 1 = 10-16; 1 =16-20; 1 = 45 & up females 1 up to 10; 2 =10-16; 1 =45 & up One of his daughters is Susannah and I recently found a photo marked Uncle Sam Marks and I am fairly sure this is the Samuel Marks born circa 1820 that resided in Tyrone, Blair Co. PA. If so this is him in the 1880 census, residing in Tyrone.
