I have never heard any information in my family about our Alexander's being in South Carolina. From records that I have they were in Lancaster Co.Pa. during the Revolutionary War. in Lampeter Twp. then sometime before 1790 they were in Cumberland Co. Pa. the after 1790 Sullivan Co. Tn. to Knox Co. Ky in 1810 to Washington Co. Indiana about 1816. My 4th-great grandfather Thomas Alexander died in Jackson Co. Indiana on August 10, 1849. He was born in Ireland in May of 1752.
