The only thing I can find is a John Eisenhauer(original spelling), was born feb,1781 and died Nov. 1861, was in Ringtown, Schuylkill Co, PA He married Eva and they had four kids Peter, John, Elizebeth and Abraham, John married Elizebeth Bowman and had One child Israel He married Mary Klingeman in 1841 in Ringtown and died in 1920, they had two kids Lydia E. and Oliver O. Eisenhower, spelling of last name changed, last known Lydia was in East Orange county and Oliver was in Wilkes Barre, I hope that helps out a little, if not here is an address you could try the Archives Division of the Pennsylvania State Library at Harrisburg, they would be in the German Pioneers, by Strassbuger and Hinke, I have a copy of the family tree from 1741 to the seventh generation and the Name Peter is used a lot in every generation up to the sixth, feel free to contact me if you need more help
