My great grandmother, Anna K. Granger Dunphy of Towanda was a sister of Burton. I grew up in Waverly, however did not know either Burton or Horace's families. I did know an Alma Granger Arnold who lived in Burdett, NY in the mid 1960s. She was a niece of both and had contact with them. My Granger genealogy info on Burton and Grace does not go beyond their children. Perhaps if you can find Alma, she can be of help. Mary K. Nicholson
