I am trying to find a Robert S. Fulton, who appears to be a mystery. I recently found a connection to Uinta, WY.

He was apparently born about 1854 in Ohio.
He married Eva M Hinman in Utah, on October 30, 1876. The marriage record says that Robert S Fulton was of Uinta County, Wyoming at the time of this wedding. He abandoned his wife and son about 3 years later (1879), so nobody knows much about him, but I would really like to trace his ancestry if possible.

The only Robert S Fulton I can find, who was born 1954 in Ohio, was still in Ohio for both the 1870 and 1880 census. I suppose it's possible it could still be the same guy - a lot can happen in 10 years.But I'd like to see if anyone can help me learn how to search other records in Wyoming, so that I might be able to get some more info about the Robert S Fulton that can be confidently connected to this story. Any help is appreciated!
