Levi Duke and wife Persis Chapin of Johnstown Ohio from at least 1820's to 1870's? Persis gives birthplace conflictingly as either NY or Mass.depending on what census year is viewed. Is there a link to Mary Electa Chapin born NY whowed Joseph Barnum in Johnstown in 1822? These appear to be very close families as the Barnum/Chapin family and the Duke/Chapin family always live within a few doors of each other in the census images. Further, in 1870's descendants of my Barnum/Chapin line are living in the home with the family of the Duke/Chapin line. In addition...Barnum/Chapin great grandson is named Levi Duke Barnum...hmmm... Desperate to ascertain parentage of Joseph and Electa and determine in what way they are related to Persis Chapin and her husband Levi Duke.
