Just to further explore I searched for Harber, Harbor, Harbour, and Harbens born in Virginia around 1792 (when KY become a state) but having residence in Kentucky around Bracken County and found a record in the 1860 census of a Thos Harber and wife Eliza Harber. They had a young girl living with them, Sarah E Harber, and a 46 year old named America Robinson (presumably a laborer of some sort). I believe Thos could be misindexed and may actually just be an abbreviation of Thomas.
Thos and Eliza were living in Nicholas County at this point, Nicholas County is in VERY close proximity to Robertson and Bracken county where most Harbers in my family have lived. Perhaps its something to pursue. Not sure yet. Thanks for your help!
