Thank you for your message. I am not sure if this is the same Joseph Acker. I have his birth in about 1839 in Trenton, NJ. I am him listed as missing during a battle on the Peninsul in 1862. His military records have him in a hospuital May & June 1862, and then as deserting in July 1862. Then he disappears for me. I cannot find anything more on him. He may have gone out west to Beaver County, but I haven't a clue. His parents names were Abram & Catharine. Do you have anything else on him?
