I am searching for the grave of Mary Ann Cogswell Skellenger (1817-1854) w/o Sylvester Skellenger (1809-1886) from abt 1835 to 1854. Mary Ann was the daughter of Geo Washington and Polly Dimmiock Cogswell of CT. Her birth place may have been CT or NY, that d/p is not clear at this time, but the year of her birth is known to be 1817. Her death is well documented as being in 1854 in the city of Watertown, Jefferson, NY. Many of her Cogswell family members, including her parents, are known to be buried in the Evergreen Cemetery, located in Orwell, Oswego, NY. Her burial site at Evergreen Cemetery has not been located; she may, however, have been buried in Watertown.
Following her death, her husband and children removed to Tafton, Grant, WI, abt 1857.
Any info regarding the location of her grave would be greatly appreciated.
