I didn't find any info about her prior to her marriage.
1860 Attic a, Fountain, IN
Luke Beaver, b. OH, 48, day laborer
Marget, b. IN, 18
William H., b. IN, 20, day laborer
Robert, b. IN, 17, day laborer
Oliver P., b. IN, 10
Luke, b. IN, 8
Samuel, b. IN, 6
Amanda, b. IL, 26
1870 Troy, Fountain, IN
Luke Bever, b. OH, 55, basket maker
Amanda, b. VA, 40
and that's the last I found them.
I'd contact the Fountain County Historical Society, www.facebook.com/Fountain-County-Historical-Society-2120
and the West Central Indiana Genealogy Research Library, www.focogensoc.org/
and ask if they have any info about them. Successful Searching!
