I have Menga Bernhard married to Adolph Gfeller on 09-Jul-1874 in Polk County, Iowa (probably Lincoln Township near Alleman). I have some information about her parents, but I have no documentation to back it up. Her father is Peter Bernhard b. 19-Jun-1825 in Untervaz, Graubünden, Switzerland, d. 20-Apr-1919 in Dickinson County, Kansas. Menga's mother is Barbara Allemann, b. 03-Mar-1825 in Untervaz, Graubünden, Switzerland, d. 02-Oct-1910 in Sheldahl, Polk, Iowa.
