Well, it's years after your inquiry, but....
My wife here in Omaha is Maureen Shanahan Crouchley. Her Great Grandfather is Martin Shanahan, son of Daniel and Margaret. what I know is on my Crouchley family tree. I'm now gathering information on the Shanahans in Saunders County. Martin's brother Malick is the one who moved here from Wisconsin.
