I'm interested in finding a death certificate, for John SHIPPY. I don't know if you have the availability of an index, but I believe he passed between 1858 and 1860. Originally from New York, he came to Elkhorn. On the 1860 census, his wife, Martha Jane Shippy is listed with two children Harriet E and Caroline, but he is not. It's also possible that he was married to Martha Jane (Cronk) in Walworth County, since she was 16 when she gave birth to Caroline in 1856.
I'm sorry if this is too general, but this is a difficult area in my research and this is all I know at the present time from my documents.
