I am trying to locate any information on Walter John Casson born in 1861 in Milwaukee, WI. He married Catherine Dohmen (born in Luxemborg, Stearns, Minnesota) while they lived in South Dakota. I'm really trying to find out who his parents were. I know that James Casson came to Day County with Walter J. and Walter's parents are from Ireland, but I know nothing else. I'm not even sure if James is a brother, father, or no relation. Catherine and Walters sons Walter J. and Francis were born in Troy, Day, South Dakota. If you have any information, I would appreciate it. I've already found the census on ancestry.com that lists him as We??? Casson. They left Day County for Harwinton, Connecticut sometime in the early 1900's. Thank you for any assistance you can provide.
