I am Andy Pfost, son of James, grandson of Wayne. I believe we have a relative of Valentine but will have to ask. I have 2 children a boy and a girl.Let me know if there are any Pfost's from Kansas or Idaho. I believe my great grandfather was a son of a lady with the last name of Brown but Mr. Pfost was married and had a an affair with her. Her son was given Pfost as a last name.
