Mr. Bean was born in New England about 1805 (based on wife's DOB).
I could not find any reference in Ancestry.com, Family Search, FindMyPast, Findagrave, or via Google search for a spouse with the last name Bean.
There was another Emily Avery married to Christopher Avery. Her maiden name was "Walker". See FAG memorial #108053581. Her parents were Elijah Walker and Lucina Colton Walker.
Also, on Ancestry.com, there was a Patience Avery born about the same year as Elizabeth (of this profile) who was married to Oliver Bean.
