I'm researching Watson Collins circa in S. C. Some of these Collins went into Alabama and Georgia I know.
Also, I had a aunt who married one of my Father's brothers (Roy E. Collins) whose maternal grandfather was a S. C. Day (I heard her talk a lot about "Granny Day.") These were Pickens County Days. The aunt's name was Jewel Sheriff Collins (b. 1909 d. 1998). Her Mother was Lydia Day. Granny Day, I believe, was a Stegall. She lived to be almost 100.
If you have any interest, I can put you in touch with a first cousin who could give you more details.
I also am kin to the S. C. Mannings and the Manigaults. Gov. Richard Manning (SC) gave land to some of my Collins ancestors.
