Find Ancestors

Hi I am trying to find out more about my husband's father and family. His name was Francis (Frank) Richard Wilson, born abt.1919 in Allora, Q'ld. Australia. He married Edna Millicent Lauchlan in Brisbane, and their children were :- Dennis Richard born 10/07/1943 Colin Francis born 22/10/1944 Frank and Edna separated when the two boys were approx. 18mths. and 6mths. old - they never knew their father. He is believed to have gone south to live. We know of a another family in Melbourne, his partner was Lesley and there were (4) children. He died aged 51yrs. in Melbourne Victoria. My husband's mother died in 1988 but she never spoke of Frank to the boys so all he knows is what is on his birth certificate. Frank and Edna were never dirvorced, but both had other children to their partners. If Frank Wilson or family from around Allora, Q'ld. are in your family tree, please contact me. We know just about everything about Edna thanks to some very wonderful cousins of Dennis & Colin's and are now very much in touch, but we would like to complete the union by knowing more about their father and family. Frank has (4) Grandchildren and (4) Great Grandchildren in Q'ld. Cheers, Rita (Dunstan) Wilson
