Alan, I also believe that our family lineage links to the Blackheath Thews,my father Rexford William Thew lived and grew up in the Granville / Parramatta area. His father William passed away when I was about four or five years old,we had moved to Raymond Terrace north of Newcastle N.S.W. at that stage, I also believe there is other relations living in the region some I know that are my fathers cousins family. My father always told us he was related to the Blackheath Thews, my daughter Kylee lived at Faulconbridge and Katoomba for a period in the early 2000'S.I now live in Melbourne Vic. as does my brother next to me, my other brothers live in W.A. and Qld. my sister still resides at the family home in Raymond Terrace. I can provide limited further information if you require.
