My name is Ron Paul.You and I have some similarities with who we are looking for.Let me tell you a little of the information that I have.
I have been given two possible surnames of my grandmother. Here name was Maggie Thomas; but I've been told she also had the surname of "Mahadeo."Maggies father's surname was Mahadeo but the children allegedly changed their last name to Thomas.This is very close to your Mahadei which is what peeked my interest.
According to my records, Maggie was born on Jan. 10, 1910 in Mt. Rose, Grenada.She died and was buried in Roodal Cemetery in San Fernando, Trinidad.
Now, Maggie was married to a well-known spiritual figure in Trinidad.His name was Norman Paul, who was born in Mt. Rich, Grenada around 1888 or 1897 (don't know for sure).There was a book written on him (Dark Puritan) and he is listed in a number of Encyclopedias of religion.
Norman and Maggie had 5 children: Linton, Leslie, Finster, Oster, and Valerie Paul.
