Eliza Ann "Eliza Jane" Felts appears to have had 2 husbands and children by both men. I'm finding descrepancies in the timelines. I'm showing an Eliza York in the 1860 Census with William Lewis York and 4 children.
In the 1870 Census she is living alone and with her children (according to what I've found so far, William died in 1862) and showing to about 40 years.
In the 1880 Census she is living with Thomas Harris with other children, but she was 50 years old - AND would be too old to have these children. Also, some of the birthdates of the children cross with the York children.
She was living in Davidson County, Tennessee. I think this is the same person, but don't know how to show the differences.
