Lookind for Decendents of Thomas Purnell

THOMAS PURNELL was my grandfathers brother he was born inHindley Lancaster on the 17/7/1890. MY grandfather PAUL PURNELL came to Australia in 1914 and I am told THOMAS came out several years later.
I have no knowledge of him and his family since. I have been told that they stayed in Walloon near Ipswich Qld with my grandparents
but I have no other info on them since then.
