Asking this question, because it gives us something to aim at finding. Having a question, helps us to know what question we need answered. Am expecting it to be an extremely difficult answer to find, and probably require DNA to find a satisfactory answer.
Background to this question. We established satisfactorially, that Reginald's mother Bridget was in Adelaide around the time Reginald was conceived (Jan 1886), and moved to Melbourne (Mid 1886). She married in Melbourne (1887), to James Keane, who was married in Melbourne (to someone else) at the time Reginald would have been conceived in Adelaide. James' wife and child died before he married, and took responsibility for Reginald.
The other hints that we do have, is the LNAB given on Reginald's birth certificate, is Morris, which doesn't seem to be from Bridget's family, and so may be from Reginald's father. Bridget's maiden name is Mongan.
So, a DNA update. Keryn and I have somewhat of a triangulation of DNA results, which seem to be successfully isolating cousins from that segment of the family. We both seem to have an unexplained higher than expected percentage of Swedish / Danish, but don't particularly have an explanation. We also have somewhat of a list of surnames that seem to keep coming up with these connections: Taylor, Ward, Crowther, Lees, Farrell, Brennan, Nesbitt, Davis, Leibich, Johnson, Carter, Nicholson, Moore, Williams, Starr, Singleton, Myers, Humphrey, Green, Robbins, Jones, Martin, Richards. There are many more, of course, but these ones seem to come up multiple times across the cousins we have connections with. Not to mention, Green & Carter coming up in a Y-700 search. Not sure how much closer we are, but hopefully some progress.
Have confirmed with someone our connection beyond Reginald. It confirms a connection with the Herbert surname, which seems to be closely connected with Taylor, Ward, Crowther, and possibly Nesbitt. Those with similar DNA, seem to have some similar names in their tree. These would represent either the paternal or maternal side of Reginald's father's family. Using that information, I have been able to also work out a cluster of people with similar DNA, from the other side of the family. There are names such as Carter, Jones, Williams, Davies, Martin, Rees, and others. It would be great if one of the cousins would actually respond to my email though. We are looking in either Adelaide, or the Gawler area of South Australia.
