Catharine Oakley married to Silas Alger

I am looking for any information on the Catharine Oakley who married Silas Alger. Catharine was born on July 5, 1817 in Rensselaer County, NY; she died on December 17, 1892, in Fly Creek, Otsego County, NY. Her father may have been a Josey Oakley who was listed in the 1820 census (Stephentown, Rensselaer County, NY). He does not appear in any other record or census that I can find. Catharine's death certificate records her parents as unknown. Any help in regards to Catharine's parents would be greatly appreciated.
Catharine and Silas Alger are my 3rd great-grandparents.
