I have found some information on Patrick McManus: his death certificate and obituary. It is on the Martin family tree I have. Here is the link to Patrick's page http://trees.ancestry.com/tree/40368236/person/20349914221
I have asked my husband about Patrick but he doesn't know anything about him. I know that several family members went to Traverse City a few years ago to do research on the Gore/McManus family and I will see if I can find any info on that. I do have some pictures that I will email to you. I have attached a photograph that includes Roy Gore; that would be your father's brother. The back of the photo reads Frank Martin, Walt Woods and Roy Gore. Not certain who is who but maybe you can tell? Also a photo of a Ted Martin; maybe this is Maude's son Ted? I may call you in the next few weeks as I gather more information. Unfortunately, my mother-in-law passed away just before Christmas and she was Maude Gore's last surviving child with Frank Martin. So a lot of family history went with her. However, she did leave a lot of family photographs and memoirs behind so I will see what we can glean from that. We have only just begun to sort it out.
