The 1934 Descendants of Gov William Leete book shows #460, John Leete, as having a son Duron. Turns out Duron is really Duran A. Leet, born in NY in 1854. This is a missing link in the Gov Leete genealogy. Duran, who moved to Waverly, in Bremer County, Iowa, had 7 children.
John Arthur Leet was the first born of Duran and Alice (Miller) Leet. He was born in Waverly on 12 Sep 1880. I'll write a synopsis of his descendants, what I know and don't know, after a review by one of his descendants.
A rough draft of "Descendants of John A Leet (1880-1942)" is attached.
