We can ID another Tennessee Pryor marriage. The Nashville City death record for Mary Abbey Gill born 1839 states her parents were William Pryor born in NC and Jane Hopkins also born in NC. I found the Gill family on the 1910 Census in Nashville; at that time her mother’s place of birth was recorded as AL.
I agree with online researchers who’ve matched her as the daughter of William and Jane C Pryor who were counted on the 1850 US Census in Lincoln county, TN. This was further confirmed by looking at the 1870 Census — Mary and her husband Charles W. Gill were counted below Jane Pryor’s household in Lincoln county.
I’ve updated Mary Abbey Pryor Gill’s memorial on Find A Grave.
