Hi Mark, Finally found the right person.But, like you, can't find anything past 1910.The online Wi. indexes are not in the right time-frame.
I see where Margaret and Homer were adopted.Moritz/Morris was a clergyman. So that moved them around a lot.
Only guess would be to try and find an obit for Moritz, Josephine or Homer.Can't find anything online. So maybe the "old fashioned" way.Writing letters or a call to the city or county libraries where they were last found.
