Hi Shorty: My husband's family is also from Barnwell area. His name is Carlos "Carl" Stratton Deer. His father was Paul S. Deer whose father was Aquilla Deer from the Barnwell area. They are related to Big John Deer who sailed with Cpt. Kidd.Mary Marg.Deer may be related to that bunch. I have not heard the Arnold name in the family and I've been a part of the famly now for 31 years. There is a book about the Deer Family written by a woman in Michigan so I've been told. Also, you need to contact Fred G. Deer at CDCBDEER@aol.com. He is the family historian and can give you alot of info. Tell him I sent you.
