John: I do, indeed, have a copy of the will of Robert Daniell of Horry County. I wrote the names as mentioned in the first posting.It is a long will/too involved for me to type it all. I may have copied his will when I was doing DAR research in NC. Can't recall for sure.
One of the names you mentioned caught my eye: the Melton family.
William Daniell 1743-1840 m. Mary (Polly) Melton.I have a list of all of their children.
If you think this is a Melton-Daniell union relating to you, let me know and I will put you in touch with a Daniell researcher who knows much more about that particular lineage than I.
