My mother, Euteva Geertsen, FKA Witham says yes! She has war records. Grandfather Joseph Witham served for the north in 1862 as did Otis R Witham and James. Otis and James were captured and spent 2 years in the South prison in Texas. Joseph got seperated from his unit and walked miles to find them. He was declared a deserter but when he and his unit were reunited, he was reinstated. The war ended in 1865. Hope this helps!
