Hi, Have you tried doing DNA to find other family Member. you can find a lot of new cousin way,that's why I did it.. I'm from Upstate NY Dunn's. But have never heard of any of them names that you are looking fore. I'm looking for any Dunn's who could be related through the Dunn's too. our 4th Great grand father George H. Dunn come over from WhithornShire ,Scotland,in 1774. to Stillwater Saratoga county, NY . where some of our family still lives today. there are so many Dunn's in the US with the same first name.
well good luck with your search
