I was good friends with a lady who came to live in Australia in the early 1960’s. Previous to that she lived in London after moving there from Grenada, WI.
Her name was Carroll Mitchell, she never married. She had a sister Marguerite Waddington (nee Mitchell) who lived/lives in Melbourne, Australia. She had three children, Debbie, Fiona and Nigel.
Carol also had a sister Denise Mitchell who was a Doctor (I believe), and was married and living in Jamaca. I met her when she visited Carroll and Marguerite in Australia.
There were two other sisters. One who lived in St Lucia. I can,t think of her name unfortunately. The other sister married a Doctor and moved from London to Tasmania, Australia. Her married name was Brown.
I also met Carroll's mother who came to visit several times. She was very elderly when I met her. She was a pharmacist In St George, Grenada.
There was also an Uncle Ewart, who used to play golf and who came to Australia to watch the cricket.
Hope this may be of interest to you
