It's possible that maybe he's a cousin to my Bartletts. I don't know who Jonas Sr.'s parents were, nor what siblings he had. And it's interesting that you mention the last name Zimmerman, because one of my Bartletts married a Fannie Zimmerman. Unfortunately, until I can ever find anything on Jonas's parents and siblings, I can't say if there's an actual connection or not. All I know about Jonas is that he was born in the 1790's in New Hampshire. As far as I know, all of his children were born in New Hampshire (I was told Cheshire County, but no one can seem to find any info on them in that county), and then in the 1830's they moved to Genesee County, NY. Elias was in Oswego sometime in the 1840's, as he was there in 1850 census.
