Hello!
I am a G- G grandaughter as well. I actually have the marriage certificate of Andrew J. Beller (not ar because of the name change during the war) and Mary E. Troutman. I also have the civil war discharge papers on Andrew J. with the old spelling. The stroy of how the family name got changed was told by my great uncle for years! Let me know if you want copies of these. I have many tin types of one of the wives and Andrew.
My maternal grandmother is daughter to Earl, son of Andrew.
