I think that the O' was droped before they came to the U.S.
Samuel was son of Robert and Ann Reily, who land in So. Carolina. in the 1760's. Also so I am not sure if this Samuel had a "W". Later there is Samuel Warburton, but I do not have any information to show that there was a "W" with Robert and Ann's son. They left S.C. and some settled in Ga., I do not know of any in Ala., then to So. MS and So. LA. If you have been reading the message board, I have now found Ben Day Reily. He is from So. LA, now in Ala., and knows where Samuel Reily (M. McD.) graves are, near Clinton, LA. Send me an E-Mail at <owr3@hotmail.com>. Samuel Warburton Reily was my Great Grand Father's brother. They lived in Morehouse Parish, Louisiana, Collingston and Bastrop area. I was born in Bastrop, but now live in Columbus, MS.
