Looking for DEGANNES

My great grand mother was CATHERINE DEGANNES and she married MARTIN MCMILLAN. My grand mother was LOUISE NCMILLAN and she was married to LEWIS TELESFORD. I do not have any dates for my great grand parents but I do know that my grand mother was born on 19 Mar 1896 and died in 1963. I am in contact with a few DeGannes from Trinidad but the names mentioned here lived in Vincennes, St David's, GRENADA.
