There is a photo on Ancestry of Stephen's death certificate. It lists his parents as Ezra and Hannah (no LNAB) Hutchinson, both born in Connecticut.
Edit: Additional info - There is no date of birth but his age at death is listed as 90 years 10 months which would give him a birth date of 6 Mar 1814. Informant was William Hutchinson and his middle name was spelled with an "I" not a "Y."
