I did a search of FamilySearch.org and found a Lucinda Clearwater listed in the NY 1855 census, age 6, in Crawford, Orange County, NY. She is shown with her mother Sarah M. Clearwater, age 48 and her father James Clearwater, age 52. Using Sarah's age of 48 gives her birthdate about 1807.
In the 1900 Census, Lucinda Jump is shown with a birth date of February 1850, so her age in the 1855 census fits.
Hope this helps.
