I don't know very much about Joseph Dorrill. In my ggg-grandfather's pension record, it mentions that he served under a Captain Dorrill at Charleston. That was about the extent of what I have. The entry below was made by "ed" in the American Revolution GenForum site in response to my query about Captain Dorrill. I hope this helps. ------------------------- " Per Moss' SC Patriots in the Revolution, Joseph Derrill (also spelled Darrel) was a militia Captain at Littleton's Bastion in 1775, and was also at the siege of Charleston. At some point he was a Major. He gives as his source Audited Accounts and Treasury records in the SC Archives. "
