I also have a STILL connection, through Elizabeth STILL who married James LARGANT in Rutherford Co, NC in the early 1800's. Their daughter/granddaughter, my great-great-grandmother, Sarah Elizabeth LARGIN married Samuel Allison WATSON and they removed to Weakley Co, TN after the Civil War. (We've found Sarah Elizabeth and her sister listed in James LARGENT's household in 1850, but still haven't determined whether they were his children, or belonged to one of the 11 children listed in James' will in 1858.)
Anyway, our Elizabeth STILL is supposed to be the daughter of Bozias STILL and Mary LYDA, who had about 13 other children. One of those was Andrew STILL, b. 1803, who married Sally BRYANT. The only child listed for these two in information I received from another researcher is George Washington STILL who married Jane Elizabeth MORGAN. Is there any chance this might be your G.W. STILL?
I have a lot more info on this line, if you think it might be a connection for you. I'd also reccomend you check out the link below. It will take you to a site called "Still Searching." The URL is: http://www.isd.net/dcurtis1/
It's just loaded with info on STILLs from all over.
Interestingly enough, I also have a step-connection with a MINTER family who were in Jefferson Co, KY before moving to Madison Co, IL. I assume MINTER is your married name... but wonder if you know anything about your MINTERs...?
Hoping to hear from you soon,
