Your write-up of the history was a real pleasure to read.I'll follow up on your suggestion to investigate the Valentine - Sussanah line.
In the meantime, I worked with Lydia's saying she was from Buncombe/Yancey Counties.Since Yancey was formed in part from Buncombe in 1833, and Lydia was born 1829-1832, I checked the census.(Buncombe County records burned in 1830 or so.)I found no Holifields in Buncombe in 1820, 1830, 1840 or 1850.In Yancey in the 1840 Census, there are William A. is age 50-60; Jacob is 40-50; and Daniel is 30-40.
I wonder if anyone has something on this group of Holyfields.
