Hi just a quick update....I spoke to my Mum, and she remembers Augusta Linton, who married one of the Wallaces. She used to know him by the name of "Gussy". My mum says they are related, but she is not sure how. She said that "Gussy" went over to England to live for awhile, then returned to Jamaica, where he eventually passed away.
My Mum also says that most Linton-Duncan-Cammock family are connected in someway.
Hope this was of help to you.....my mother and your grandfather Augustus were related, if I get anymore details, i will let you know.
p.s. my dad grew up in Trysee, and he had an encyclopaedic knowledge of the family, in that area. Sadly, he has passed away, but i am certain that he would have known Mabel Alexander. I will ask other family members about Mabel....
