I had done some searches for you and come up with nothing. There is not a lot of information to go on.

Information on your mothers and grand mother maiden name, also birth dates for your grand father and location would help.

I assume you are looking for Edward Louis Fisher who married Rebecca Mcgaughey.

Do you have an approx date and place for thier wedding ?

my mothers maiden name was beverly hall and my grandmothers maiden name was Anna Mae Blakeslee, and my grandfather was born on august 7,1914 in Lima.Ohio in Allen county. Rebecca and Edward was married in Lima,Ohio between 1912-1914

I found this Registration for WW1. On the Draft he is down as single. How certain are you that he married in 1912/1914.
