Conrad died in 1818. His Will names Jacob, Richard, and daughters Magdalena, Margaret, Catherine, Dorothy, Sally (wife of Joseph Bowers), and Eva.
~"Early Families of Herkimer County, New York: Descendants of the Burnetsfield ..." By William V. H. Barker 1986

Sally and Eva are named in the will as Conrad's two youngest daughters. The probability the girls were twins is high in our family line.

The following children were not in the Will, nor has further record been found, and it is presumed they died before 1818:
Conrad
Henrich
Gertraut
Elisabetha
Mijnhard
Johannes
Maria

Per family records, Maria Catharina Grimm Casler died August 14, 1829, and is buried in the Dutch Reformed Church Yard at Herkimer, New York.
