Heather; The name should have been Ephraim Courser the father of Rosannah Courser Kolts. I didn't notice my mistake until the message was posted. They are in the 1920 Census for Aberdeen City, Washington. Aren't there any Bible records that might help you? How about death certificates? That might list Robert's father if the person that gave it knew. We have known very little about Rosannah. I do have some pictures of them if you don't. Sincerely, Elaine C.
