I am trying to find information on Sophronia (Rolf) Darling, who was the third wife of John Darling. John was born in MA in 1787 and died in 1859 in Oregon. These people were very early settlers in Otto, New York and they migrated to Fayette County, Iowa in 1853. I can trace Sophronia up to 1870 and she seems to disappear after that point. My info says that she died in July of 1892 in Union, Iowa. Is there anyone out there who has information about her from 1870-1892.?
