Glad to see your mum is a feisty as ever muffett my mothers name was Nancy as well her side of the family came from the Wagin/Kataning district in W.A the Williamsons of whom I think a couple may have served in the 10thLH and the 25thLH (posted pics of the hat badges/collars ages ago) sadly I am unable to clarify it now, my dad was from Plymouth in Englandcame here by himself in 1929 as a 16 y/o to be with his brother at their mine near Coolgardie. It was called the "Snake Pit" still have about an Oz of gold in natural form he dug up all those years ago.
No matter what goes on in life you only really have 1 mum & dad.
