Child I's paternal grandfather was still living in 1939, aged 69. He had a Normal School education (South Dakota) and was teacher, farmer, and small-town merchant. His education was superior to that usually achieved by farm boys. His special interests were church, travel, and repair work on his own properties. He is described by his son as stubborn, thrifty, and industrious, with uncompromising attitudes toward worldliness.
I's paternal grandmother died when I's father was 9 years old. She had been a teacher of music and kindergarten, and a housewife. She was educated in a Normal School and a Conservatory of Music. She was an active leader in her community, established her own kindergarten, and was socially and musically active in local ways. Her home was in South Dakota and her father was first Land Commissioner of Dakota Territory. He had led a group of homesteaders into that region about 1860. He was politically and educationally active--Commissioner of Immigration, Commissioner of Education, in the Territory.
No mentally defective or otherwise generally incompetent relatives on the father's side are known. The great-grandmother of I, on her father's side, is said to have been a relative of Phillips Brooks.
I's maternal grandfather was born in Texas of ancestry half French-Huguenot and the rest German-English. He was a high school graduate. He was in later life a merchant and real estate operator and active in community affairs.
I's maternal grandmother was born in Oklahoma, her ancestry being French-Huguenot, Welsh, and Irish.
