Hi Elizabeth, I don't have an Indiana Counties Map so I don't know what towns Dearborn covers. I have living Louden relatives in Linton, Rising Sun and Indianapolis area.
My Grandfather raised his family in Clinton but he was born in Rabbit Hash Kentucky to William Louden and Savannah Bailey. It is likely that William was not born in Rabbit Hash. He was a musician and traveled until he decided to settle down and raise his family in Rabbit Hash. He had 6 children who grew to adulthood but only 2 of them had families.
