Dear Jeanne, I'm also researching Dumond. My link to the family is Archer G. Dumond. He married Elizabeth Martin.The town of Belmond is named after a daughter (Belle) mond comes from Dumond. Belmond is in Wright County, IA. Their daughter Emily Dumond married Thomas Sheets. Edwin Sheets their son married Emma Grove. The names I'm researching in Seneca County are the following: Dumond, Sheets, & Grove. I have some old photos of the Sheets and Grove families, if anyone is interested, I'd be willling to share.
