This is the information that I found at the Clarendon County archives on the Fullwood Family:
William Fullwood also as Fulwood
William Fullwood was Captain of a Company of Volunteer Militia by 9-30-1775. William Fullwood's son Federal pensioner William Fullwood Jr, stated in a letter dated 12-10-1844 that his father was promoted to Major and was stationed in Charlestown when the British attacked Fort "Moultrie" [Fort Sullivan 1776] and he resigned, due to age, between that time and the British returning again .
A family record of births, probably torn from a Bible, also in his son William's pension papers states that William Fullwood Senr. was born 2-12-1735; his wife Sarah was born 1740, no month or day given. He may have been alive on 1-15-1794 when as Major William Fullwood, his land was bound by other land. He was deceased by 1-1-1795. His widow Sarah Fullwood of Salem died testate beween 11-2-1814 and 2-16-1816, naming among her children, two daughters who were not in the Family Record.
