I suspect a dau of Eliphalet Robinett b. 1875 Maryland and Eliza Chaney Robinett to have married a LOGAN man. I have no idea of their first names though...
In the 1870 Lee Twp., Athens Co. Ohio census there was a BRAZZILLA LOGAN (a boy) aged 13 b. OH living with Eliphalet and his wife and two other of their grandchildren, Julia Warehine aged 3, and Eliza Knowlton aged 14.
I searched the 1860 census only to find a male child named PERSELLA LOGAN aged 3 b. OH, living in Meigs Co. with Samuel Logan aged 58 b. PA, Mary E. aged 22 b. OH, Daniel aged 19 b. OH, Samuel aged 17 b. OH, and Jacob aged 14 b. OH. This census does not give relationship, so have no idea if this Samuel is father to Persella Logan or not.
If this family rings any bells, please contact me. Thank you, Marcia
