Hi - good to hear from you. My name is David Alden and my wife of 41 years is Rubie (nee Meghoo), twin sister of Vie, who lives in New York. We live in Florida.
Rubie's parents were Hannah (nee Mangaroo, born in Grange Hill, Westmoreland) and David Meghoo (born in Guyana) and all the grandparents (your great grandparents) came to Jamaica and Guyana from India, I think around 1900.
I believe Harry's father was Percival, a brother (or 1/2 brother) of David, so Harry and Rubie are 1st cousins and you are her 1st cousin, once removed.
I have tried to research the Meghoos and Mangaroos but it's a brickwall when it comes to Guyana and India.
Lets talk further on our private e-mails - mine is email@example.com
Looking forward to hearing from you
David and Rubie
