Wolfe
Gertrude Wolfe was the wife of Wm Darlington Smith. I have had a hard time locating anything on her or her family.
Just recently I have found Wm Darlington's obituary, and in it it gives Gertrude's middle name as Ellen.
So in searching the census', I have found the following on the 1880 Census:
Wolfe, Jacob-------W-M-------age 28-------Laborer
Ellen-------W-F-------age 26-------Keeping House
Gertrude-----W-F
-------age 8-------daughter
They were living in Perry County, Saville Township. So with her middle name being Ellen, I am assuming that this is the right family.
But I may be wrong.
