Smith Co. TN , Craigheads

Hello everyone, have taken a break from doing my own research on the Dillehay family to investigate the Craighead/Craghead family. Several Dillehays married Craigheads and there is quite a few descendants still living in the Smith Co. TN (Defeated Creek community). Maybe some of you all can help me with where my bunch fits in. Here is what I know. My husbands gg grandaddy Dixon Alexander Dillehay married Mary E. Craighead she was the daughter of Obediah Craighead. Obediah's father was Peter Craighead and I think Peter's wife name was Jane. Peter had children name of Cyrus, William Harrison, Charity Craighead McClellan and Obediah. As I said before Peter's son Obediah married first to a Mary? and they had at least two children a son named German T. and Mary E. (Dixon Dillehays wife). Obediah's wife died and he married again and had several more children. This is basically all I know.
Can anyone share what they know about a Jefferson (Jeff) Craighead who was raised by a Reece family. Jefferson uses both last names on paper and he has lots of relatives who are still around here. Some use the Reece name and some use Craighead. Our local cemetaries have it spelled Craighead. Have only seen one grave where it is spelled without the I. Hope to here from some of you all soon. Thank youMrs. Terri Dillehay
