Not sure if this helps but....
I recently found an entry for marriage for Harvey (
Yancy?? It's hard to read)
Morelock & Emmeline
Morrison 2 June 1876.This would fit better with the birthdates of SarahT, Rachel Martha Ellen ,etc.
I also found the divorce entry in the chancery records for 1898.
To confuse matters further I found a marriage record for 1891 for John Harvey morelock & Emmeline
Morrison for 1891.
In the 1900 & 1910 census Emmoline
Morelock is listed as a widow.
Another
Morelock researcher lists John Harvey
Morelock as dying in 1948. But i'm still not convinced it's him. in the obituary there is no mention of "previous family". Although the dates could fit.I also have the obituary of Sarah T which mentions
Cleve and Rachel Martha Ellen.
Any mention in your letters of Emmoline? I am descended from her sister
