Flynn-3288 and Flynn-1576 are not ready to be merged because: I have reason to believe that he is a brother of Mary (Flynn) Flint, who resided at Gracemere in Rockhampton, Queensland. I do not yet know who her parents are and need some more information, but Yes, they do look like the same person. If you happen to find out any more about siblings of this person it would be much appreciated. There is a family story that Errol his son, stayed with Mary (my grandfather's paternal grandmother), for a while before moving to New Guinea and then on to USA...she called him her nephew, her brother's son.
