Jennifer, I have just received this from a German von Bargen I've written to.Do you think you two are from the same line? He writes: "Another documents from the 1930ies states that one of my ancestors was Christian von Bargen, born 4. (Jan or Jun) 1826 in Otterstedt, died 28 Mar 1894 in Hamburg and his father was Wilhelm von Bargen, married with Anna Dorothea Catarina Großmann (or Grafsmann)."
Let me know if this coincides and I can connect you. Gail Von Bargen
