The Benjamin Archer and DeLozier Home Page

I am researching the Benjamin Franklin Archer family and descendants. Pre-American Revolution I believe they were in the area of Antrim County Ireland. Coming to the US as British Loyalists they are believed to have settled around Chester County, South Carolina. Thereafter, (sometime around 1805) they left that area and were given land in the Abacos, particularly on Marsh Harbour and Man-O -War. My descendants then came in 1839 to Key West, Florida. Other names that appear in my family are Weatherford, Pyfrom, Pinder, Albury, Key, Curry, Roberts.
I am also searching the DeLozier family from Sevierville, Tennessee. The spelling of the name shows up differently in some records and I am having trouble at a certain point determining who is a relative and who is not a relative. Some other spellings that appear are DeLeasure, DeLosure,....Unable to determine for sure where the family immigrated from when coming to the United States. Have access to a book by Robert C. DeLozier which has much information but not quite enough.
