Many thanks to everyone who helped me, especially Larry and barbdale. Today, I received a copy of the obit for William Groves who died in Nevada City on Jan 22, 1898. The obit was published back in his hometown of Brookfield. It was the correct William as it names his siblings. Larry was the one who got me on the correct track, but I couldn;t get the date of death from Nevada City or from the cemetery where I found the family. In the meantime, I have found the death of daughter Sarah Ann in 1944, Larry gave me the date of death of wife Mary Ann, but still need the death of Carrie G. Groves which is after William's death. We know that Joseph died abt 1879 but don't have the exact date.
