I know of a William (Will) Potteiger b.1866 d.1912 in Dauphin Co. He used to cut wood for the railroad and died when a tree fell on him.His brother Aaron b.1867 is my ggf. Their father is John Potteiger b.1833 d.1876. Their mother is Eliza Gipple b.1836 (daughter of Jacob Gipple b.1808).
I don't have any information on John's parents.If anyone has a clue I'd be glad to hear from them.
