My paternal grandmother was an active DAR and member of the Mayflower Society. She did most of the serious research for the family genealogy records.
My two great-grandfathers who were born in the US were too young to fight (one was 9 when the war began, the other one born in 1863), while the other two lived in Europe. I had a great-great-grandfather who was a Confederate but have no photo of him. Another great-great-grandfather was a Union soldier and I have a photo of him but taken many years after the war.
