The cemetery in Truxton, New York has a large monument near the center. One of the families noted is Pierce. There is a notation for John Pierce, and his first wife, Anna Stewart, she died 1838. My assumption is that this Anna is the daughter of Hugh Stewart, who is buried in the same cemetery, in a section of older stones. I also found a Charles Stewart (died 1848) and a Luke Stewart (died 1848) although I am not certain these are related (visit to Truxton cemetery, March 3, 2002)
