Ann, I was able to finally check my records and I find only John and William listed as siblings. This of course doesn't mean there weren't any. William and Betty Anne Rowe son Oliver, was born Jan 7,1800 in SC and died June 14, 1873 in Chambers Co. AL His 2nd wife and He had the following Children:
Elvira Towles born Feb 16, 1806 in SC and died May 7, 1890 in Tallapoosa Co. AL. She married James A. Germany Sr. James and Elvira were my GGG-grandparents.
Morris Gwinn Towles born Aug 29,1808 in SC and died in 1877 in New Orleans. Married to Mary Fanning Favor.
John Culbreath Towles born Jun 20, 1813 possibly in SC and died Feb 11,1877. married first to Catherine W. Barber and then to Lousia C. Darden. Louisa was the niece of Stephen and Elizabeth Darden Heard. Stephen was the First Govenor of Georiga.
William H. Towles. No information on William except he was born about 1815 probably in SC and later lived in Chambers Co. AL.
I hope this is of some help to you. If any one sees anything wrong with this info please let me know. Thanks, Kimbal Taylor
