Hello.It had been unclear how she was related for a while.My grandmother's grandmother was a Avis Abrams/Abrahams, and Florence was my grandmother's aunt.We didn't even know our great-grandparents last names until I started doing research a few years ago.My mother was a young child when "Aunt Flor" passed-on.I only know the stories I've heard and trust me, they loved her and she loved my grandmother, Millicent "Gwen" Dixon.I am told that she was very "British" in her personality.She would always tell my grandmother "the girls must know how to prepare tea."The last time they saw her she took public transportation and walked over to hand my grandmother a platter she had for many years, perhaps from England.
She had married a Carnegie and was very wealthy.They left Jamaica for Cuba and the government there took everything!Because of her loyalty when she returned to Jamaica the Catholic church allowed her to reside with them until her death.I don't know what happened to her husband.I am told she had sons.
The other names you mentioned are familiar.
I hope this helps.Let me know what else you know of her and other Abrahams.
