Henry Lee-Thomas was buried in Belgium.
Some years ago a cousin from Australia, Margaret Lee Haag (cousin to Alan Lee who we visited in 2008), went to Belgium and found this war Memorial. Margaret was instrumental in finding me and my brother Stephen Lee-Thomas and connecting us to the family in Perth. She went on a search for living descendants of Henry Lee-Thomas some years ago. The family in Western Australia knew nothing of Henry's descendants except that he had married Ruby Thredgold. She kept up her search until she found Steve and I in 1995. She died a few years later and gave all of her genealogy information to Alan Lee. Margaret and Alan are both my second cousins.
The war memorial can be seen at the below link.
