I am chasing any information on the origins of "Thomas Cooper" who married "Florence Isobel Brooks(1890-1952)" in Launceston about 1913. I have his daughters marriage certificate which shows him as "Thomas Mathew Cooper". Also his wife's death certificate which has him as "Thomas Cooper". He moved to Melbourne about 1916 with the youngest two children then had another four. He died after his wife who died in Melbourne in 1952. I am unable to find his death certificate.
