Andrew Jackson Chaney and Milbry Amelia Partain are my gggrandparents through their daughter, Lucrecy Francis. After Lucrecy's death, her husband, Silas Stephens, married Mary Ann York, whose late husband was William Hubbard Partain, Milbry's nephew through her brother Daniel.
I'm wondering about Eveline, whom I have as born c1800. It appears there may have been two couples named Hiram Partain and Eveline, for an 1860 census lists Hiram (b1798) and Eveline (c1820), which would rule out Milbry, Daniel, and William Haynes as their children. So either the six children I have for Hiram have different mothers, or they are of another couple.
