I have examined the Tasmanian Pioneer Index (births to 1899) and the Tasmanian Justice Dept BDM records (births available to only to 1905) and NSW BDM records (births available only to 1905) and have not identified any children of Arthur Thomas ALLEN and Annie Ethel (or Ethel Annie) MALEY other than Archibald Roy (1902). I recently obtained the contact details for 2 of Ruth ALLEN's daughters who are alive and on the ball at 92 and 83 years and shall ask about the above.
Coincidently I have just returned from visiting John ALLEN's mother and brother. John is sending me their family research so that we can combine our findings.The parents of William Herbert, known as Herbert Henry (1884-1963), Arthur Thomas, Clara Louisa, William Charles and Ruth Allen were Charles ALLEN and Catherine DRISCOLL. I have quite a lot of information about the DRISCOLLs but have as yet been unable to identify the parents of Charles ALLEN. John ALLEN has suggested the father was also a Charles ALLEN who married twice, Caroline OXFORD and Maria SMITH. However, he does not cite any references for this and his brother is going to ask John what basis he has for this attribution.
Thanks for adding another twig to my copy of the family tree. I will keep you informed
