1900 Census shows an Aline born 4 1864 as a widow living in Wayne Allen Indiana with Margaretha 10/1886, William F 9/1888 and Alice A 8/1890
There wise there is a Fred 5/1834 and Angeline 2/1839 (she had 11 children with 7 alive in the 1900 Census) in Wayne Allen Indiana living with Fred 7/1862, William 5/1878, George 2/1883. Fred immigrated from Germany 1855 and Angeline immigrated in 1856 from Germany.
Do any of these maybe help? I couldn't find anyone in 1923 that passed. I did find the wedding information though which you must already have.
