I am assisitng my second cousin Irene Oliver Flowers in researching the surname Oliver. We we both born Olivers. She is a serious researcher and her investigation has been extremely professional. She works on this nearly fulltime with her husbands help. She can tell you quickly if our Olivers are connected. She has gone back to the late 1700's to the birth of our common g-father named Charles A. L. B. Oliver. He had 4 wives and many children and mainly lived in Florida and Georgia. It is worth a shot. Her E-mail is, hmf@svic.net. Good luck. Please let me know if you contact her, and the outcome. Hope I helped.
