John Acker is my gr.gr.gr.gr.grandfather. I know that he was born around 1771. However, I have run across several different gedcom lists that include him but list his father differently. In one his father is listed as Jacob Acker and mother is Eberhardina Acker and his birth as 8-3-1771. Another listed his father as Philip Jacob Acker (the son of Jacob and Eberhardina). This one listed his birth as 1773. Now here is where it gets sticky. I have found reports that list Philip Jacob as dying in the Revolution. Also, PJA would have to have been 14yrs old when he had John. If anyone can help, I would GREATLY APPRECIATE IT!!!
