Hi all Thanks for the many and varied answers to my question all are very helpful and welcome. Some specific details, to assist further with further replies The birth of the first child was registered during the quarter ending June 1903. The birth of the second child was registered by the quarter ending September 1904. The parents, both single, married during the quarter ending December 1904. The bride raised her age by 2 years on the marriage certificate! The first child married in during the quarter ending June 1925, the mother's maiden surname was used in this case. The second child married in 1941; the father's surname was used in this marriage Both children had their births re-registered during the quarter ending March 1935 Below is from my 1st message viz: In 1935, the births of these two children were re-registered by the FATHER, (same volume and page number), with him indicating that he was the father, i.e he re-registered them with his surname. Nivard (and anyone ) can you please offer me your wisdom and any further comments on this matter? I do have a very poor photocopy of 1935 birth certificate of one of these two children. Column 8 of this document: When Registered says "Nineteenth January 1935, On the authority of the Register General." The words "On the authority of the Register General", appear to be the only difference between this 1935 birth certificate and a normal birth certificate. Any further wisdom and advice gratefully accepted eddie tricker Australia
