I'm trying to help my father-in-law, Lt. Col.Joseph Knipe Gastrock III, Ret., with his family tree. I'm missing quite a few dates, and I need help with some names. Joseph Knipe Gastrock II from Harrisburg, PA. was his father. Ida Irene Knipe was his grandmother. Gen. Joseph Farmer Knipe was his ggrandfather (I need his wife's name), and Henry Knipe and Elizabeth Farmer were his gggrandparents. Can anyone help me?
