Hi
I hope I've found my way to the correct board for this query

Biker has found me a very interesting will reference today which was resealed Penang, 1927.
At least two of my grt grt uncle Alexander Gordon Wilson's sons went to the Malay peninsular circa 1910-1920. Family stories say that they were involved in rubber plantations out there. I have an address of one of them from my Grandfather's WW1 diary as
Sungie Bogak Estate
Sungie Bogak
Bagan Serai
Puak
I have found that one of them returned to the UK in the 1930s. However, I cannot trace the other one, John Wallace Wilson, b. circa 1887. I gather that he married an Australian woman called Joy and they had at least two children, John and Gordon. I attempted to trace this family a while back but came up with nothing.
I have absolutely no idea how to take this family forward and would be very grateful for any advice or info.
Thanks
