My grandfather, Lavern E. Willey, was born in Rome, Lenawee County, Michigan, in July, 1912. I found his family (before he was born) in the 1910 Census there. I have the info you sent for 1930 when they lived in Fulton County, Ohio. So now I'm trying to find them in 1920 with no luck.
I'm not sure where to look and the spelling issues (Wiley/Willey, Ernest/Earnest, etc.) make things that much more difficult. Do you think Lucas County, Ohio, would be a good place to look? Lavern lived there later in life and my mother was born there.
