From what I have been putting together, the first marriage was to Mary Hunt who passed in 1865. I found her gravemarker here: http://www.findagrave.com/cgi-bin/fg.cgi?page=gr&GSsr=12...;. Also Cyrus A. and it looks like a second wife, Elizabeth (from the bio, his first wife was Louisa Fenske) are also buried in this cemetery. Also buried here are Samuel and Elizabeth, his wife, listed in the 1850 census (last name as Curtiss). I am thinking others from this family are also buried there, but I haven't put those pieces together yet.
