We are indeed related, but only by marriage I think. Your
grandmother Mary's brother, Thomas Myron Cheeney married my great grand aunt Filura Wilson in 1889.
As for information, I'll look and see what else I have, but it would mainly be regarding their wedding. I'd be happy to do local searches though, as I'm in Minnesota and I can piggy-back other research questions as well. Also, there's a wealth of info at the Minnesota History Center that's not on the internet, so I'm happy to help!
As for my end, if you have any info on Thomas Myron Cheeney and their children, that would be wonderful, as I don't know much about them. I don't even know when he died, for example.
In any case, I'm very happy to have met you (the genealogist is a lonely hunter) and am always happy to help others!
PS. Oh, if you are in contact with any of Thomas and Filura Cheeney's descendants, you might let them know that Filura Wilson was descended from the Mayflower Pilgrims on BOTH sides of her family, from her paternal grandmother Filura Grover Wilson, and of course from the Eatons, although I understand the Mayflower Society won't accept Eaton descendants because of some shoddy recordkeeping in the 17th or early 18th century. I was shocked actually, because as we all know, mistakes almost never appear in the records we study! ;-)
