This is Julie Thomson, wife of Ellis Thomson in Australia. By any chance are you the daughter of Margaret Preite (nee Thomson), and grand-daughter of Robert Ellis Thomson?
If so, PLS email me on: firstname.lastname@example.org
We have been researching the THOMSON family tree and found an old address of your mother's, but will wait and see if we get a reply from you soon!
This is SO exciting if we have found you...Ellis is the son of Gilbert Thomson from Greenock in Scotland.
Julie and Ellis
