Mary Henry Jones was my GGG-Grandmother, reported in the various federal census records as being born in Canada - more research needs to be done to discover who her parents and siblings were. She is last noted in the 1880 census at the young age of 22 while in Fairgrove, Tuscola, Michigan with her husband and 3 small children - my Great-Grandmother Lottie Viola is noted as a 2 year old in that image. How I wish I had photos of this family during that time....It is assumed that Mary passed away in this same area as her husband and their daughters, Luella and Lula children are noted in the 1900 census while living in Tuscola County, Michigan. David lists his marital status as 'Single' on this particular census, no details located to date on this detail nor when Mary passed away or if they divorced.
