Patrick - As best I can tell - Eleanor was born abt. 1813 in New York.That is all the info I have. Emmas death certificate lists her as Elenor Kimble born NY; Mary'slists her as Ellen Kimble born NY; George's lists her as Ellen Kimball born NY; and Dr. Calvin Chollett's death certificate lists her as Unknown Kimball born (it looks like) N.S. (?).
The only John Chollett's I came across around the early 1800's in NY were located in Ulster County, NY - its possible this was her father-in-law (since her husband was born at about this time also in NY) - I haven't followed up on that yet.If this is the case, maybe she was from this area as well.
Sorry I don't have more information for you.I am kind of at a stand still myself as to who her parents were.If you find anything definite or this family fits into your family tree - please let me know!
