Family lore has her first name as Lucy. No sure record found. The 1850 census has her name transcribed as "Philura". The 1870 census has the name transcribed as "Thulura". After enlarging both records to 200% the "r" could be an "s" making the name either Philusa or Thulusa which would lend support to a nickname of Lucy. Records indicate she was b.1802/1804, Vermont. her parents were Jonathan Thayer b.4/7/1753, Massachusetts, d. 2/2/1827, Lebanon, Madison, New York. Martha Smith b.10/17/1759, Hadley, Hampshire, Massachusetts, d.2/12/1827, Lebanon, Madison, New York.
I've been unable to find a birth record or a marriage record. Any help is greatly appreciated.
