Clue #3: potential baptism & parents

There is no record of Ursula's birth in the Saratoga County records or town records.  The Ritchie Files (Saratoga County Historian’s Office, Ballston Spa, NY) do not list a birth for her.

Ursula was born "about 1783."  How many years away from 1783 is "about?"  Could a baptism in 1779 be "about 1783?"  Could "Ursley" really be Ursula?

A potential candidate for her birth/baptism is:

“Reuben married ist Phebe
was received in Yellow Meeting House Sept 4 1772, Stillwater Presbyterian Church in 1792
Children:
Lydia born Oct 2 1774
Ursley born Sept 5, 1779
Son born Aug 18, 1782
Luraney Sep 6 1772”
