Frederick Charles ANDERSON

Trying to find information regarding Frederick Charles Anderson. From a 1927 NSW Australia birth certificate, Frederick is named as the father, Occupation: Labourer, Age: 39 (ie: born approx 1888), Place of Birth: Bargen, Norway,(assume this is Bergen ???) Address at time of birth of his son, 8th Avenue, Campsie. Registered at Redfern, NSW, Australia, 17th October 1927. The mother and son, not long after, returned to New Zealand and all contact etc with Frederick was lost. The son was raised under a different surname and only found the name of his natural father from this birth certificate in 1988. Family suspect he may have been a sailor ??? Any help in tracing anything on Frederick would be appreciated. Ian Hocking
