My name is Régine. I know you haven't been to your account for a long time but i hope you will see this message.
I am the granddaughter of Sinclair Bellamy, born in Georgetown Demerara December 13th 1892, British Guyana, emigrated to France.
The father of Sinclair was Abraham Bellamy and his mother Therese Power (or Poyer, we are not sure of the spelling). We think Sinclair had 9 brothers and sister. One of his sister was named Teresina (maybe a diminutive for Terese, Teresa or Terry). She died in 1957.
Sinclair Bellamy arrived in France approx in 1900. This last clue gives me idea that maybe William and Sinclair were cousins or relatives and decided to travel in the same time for Europe.
It seems that Sinclair Bellamy went first in England then in Belgium (Anvers) and finally in France.
Hoping you will answer this post, any info will be welcome, even if you are not sure of the reference. Thanks you, Cordially, Régine.
