I'm looking for information about Harry Kniffen who married Bertha O'Dell or Odell. I have Harry's parents as Erastus Kniffen and Elvira Davis. I'm showing Harry and Bertha married about 1916 or 1917. They had a daughter Margaret who was born in 1918. Bertha was institutionalized for a while. Margaret may have been also. They were in Meredith, Delaware County, NY. Bertha died in 1971 in Binghamton, Broome County. Margaret married a Morrell. I have almost nothing on Harry. I'm wondering if Harry and Bertha had any other children, or if Margaret had any children. Thank you.
