She was the mother of Solomon Seery who married Magdalena "Matty" Van Gundy, found elsewhere.
Marriage records state that Jacob Foy married Mary Van Gundy and some researchers say she was the wife of Christian Van Gundy. Others say she was Christian's sister. Hopefully someone will have the evidence to clarify her lineage.
Supposedly she and son, Solomon, lived with Peter Van Gundy when they moved to Crawford Co, comsistent with her being his daughter and Christian's sister.
If Mary belongs to this family of siblings, there is a conflict with her birth date.
Jacob remarried in Jan 1832, a Mary Lupton.
Mary was buried next to daughter-in-law Magdalena Seery.
