From an early 20th century article about Woman’s Relief Corps president Jennie Iowa Berry:
Mrs. Berry is a native of Iowa. Her father is Wilbur Riley Peet, a soldier of the Sixties, who was born in Iowa when it was still a territory, his people having been among the pioneer settlers. His love for his State is indicated by the second name of his daughter.
The name Iowa last appeared in the SSA data in 1921.
