MtKembla on Family Tree Circles

My name is Brenda Wilson. I am researching the Wilsons of Mt Kembla. I see that SaraJAne is also. I have been able to find the original Robert Wilson who came to Mt Kembla from Northern Ireland (this was a surprise). I have his death certificate and Marriage certificate to Lydia Stafford, but I can't find a birth certificate. My husband and I have visited his birthplace and have met existing family members. We have also contacted Wilsons from the family in USA and are corresponding with them. I'd be very happy to talk to Sarajane or anyone else who is researching the Wilsons of Mt Kembla NSW.
