Hi, Is it possible that the name might be LaRiviere.
What research have you already done?
Starting with the Deaths in Waterbury VT -
Registration of Death/Long form Death Certificates
may show names of parents if known to the informant.
may show date and place of birth - depends on the requirements of the time.
OBITUARIES: may have been published - may show some personal history - may show names and locations of other family members at the time.
Perhaps Sophia LARRIVEE married Joseph ATHER in the U.S.A
You have names for the parents of Sophia as Noel AL. ANIENT - was Sophia previously married to a LARRIVEE - her maiden name does not match that of the father Noel L. ANIENT
I do not believe that Vital Records,Birth, Marriage ,Death - were kept as early as 1837 - There may be church records.
