Not sure if this means a hill of beans but I have a Fuller (Marion Lee) that married into my Schulte family tree (Mildred Pauline (Engledow) Altenberger)).
From the names you have provided, the only one close is George W. & Helen M. as the parents of Marion Lee.
While the county lines were being drawn and as new counties were established, the eastern edge of Clark was part of Marathon.
?? will let you decide on this one.
