Lisa, Some of the Whitmarsh family was from New York and Canada, and some moved to Iowa. Mary Louise Whitmarsh is the daugher of Julious Dudley Whitmarsh. He was the son of Lydia Bagley and they lived in Stafford County, Kansas. Julious was married to Ida May Cotton around 1909 in Harper County, Kansas which is on the border of Oklahoma and Kansas. It is right above Kay County, Oklahoma. He had two daughters with Ida May: Cora May Whitmarsh and Bertha Marie Whitmarsh. May and Julious divorced, and he took custody of Cora and Marie. Ida May had Mary Louise in Oklahoma. I am thinking they might be related to your Whitmarshes.
