Dear Genners, I thought I'd post an update on what transpired after my 'plea' for help in contacting my newly found French family.
I received many offers of assistance >from French speaking Genners to contact my cousin. Hopefully I responded to all of them personally. If not, please accept my sincere thanks.
In the meantime the Cerque Genealogie de Juive did manage to contact them on my behalf and joyfully another cousin (whom I was not aware of) living in Singapore contacted me and we are having a great time 'connecting the dots'.
Thanks all once again Allan Jankie Melbourne, Australia
