I always thought this was neat:
How Delmar Got Its Name
On its inaugural run, rather than continuing straight through into Maquoketa as did the Davenport and St. Paul line, the Midland train paused to name the new station. In keeping with the alphabetical order of stations coming from Clinton (Almont, Bryant and Charlotte,) the conductor wanted this stop to begin with the letter "D". There were six ladies on the train with the first names of: Della, Emma, Laura, Marie, Anna, and Rose. Using the first letter of each ladies' name, they came up with the pronounceable name of "Delmar".
