Hi Esma, Exactly what information are you looking for with the birth certificate? I think you'll find the way the birth is registered means that the mothers name was Elizabeth Emily Patterson and there was no father. In other words she was a single mum. I note that Carl also had a brother George. An Elizabeth Emily Patterson married a Japanese man named Harry Fumoto in 1905. Harry's real name appears to be Kentaro Fumoto. He was a launderer. Perhaps he and Emily were separated/divorced when the children were born. The Trove website has a few interesting mentions of Harry Fumoto. Cheers, Di
