Hi. This may seem strange but following the children leads to:
John/James Coale marrying Mary Polly Vipperman in 1867
(he used James in 1870 and 1880 Census)
They have two children:
Virginia Jennie M. born 1868
George W. born 1870
Then nothing after the 1880 Census
Followed suddenly in 1900 by a James Tanner (used many different dates until later 1910s) and Mary Vipperman (b.1848) with:
Virginia Jennie M. born 1868
George W. born 1870
I'm still trying to tie this together after drawing a blank for several decades. I would love to team up with another researcher to help prove or disprove this mysterious connection.
Regards,
Greg
