Joseph and Ann Rebecca had another daughter Alice Victoria in 1908 in Tortola. The other Georges I have in my research would be Henrietta (b. Dec. 2, 1845) daughter of Henry (mason) and Hetamina Georges, Abraham (b. Jan. 7,1844) son of Andrew (laborer)and Amelia Georges of Cane Garden Bay, Catherine (b. Mar. 1844) daughter of William (laborer) and Zetey Georges, Henrietta Louisa (b. Apr. 30, 1943) daughter of Nelson Fahie (mason) and Dora Georges of Apple bay, etc.
I'm not exactly researching your family rather I am research ing people alive during that time and unfortunately I do not have Joseph but I hope this has been helpful.
