An interesting sidelight on the development of various sections of the city can be found in the derivation of the names of its streets. Principal thoroughfares in the Kingsbury area were named for prominent early land holders in the vicinity. These include Thomas K. Skinker, Robert Forsyth, Peter Lindell, Ralph Clayton, Jules DeMun and James W. Kingsbury. Kingsbury's two daughters, who married the Count de Giverville and Alfred Waterman are thereby commemorated as is the name of the head of the convent school they attended in Paris, Madame DeBaliviere. Delmar, which was originally the Olive Street Plank Road, was named by two holders of property on either side of the road who originally came from Delaware and Maryland. The coined name Delmar is made up of the first three letters of each state's name. Belt and McPherson were two early day real estate men, while Clara was named for the daughter of another land holder, John W. Burd. Pershing Avenue, was originally Berlin until World War I when it was changed for patriotic reasons. Washington and Westminster were westward extensions of streets bearing those names. Hamilton Avenue is named for former Missouri Governor Hamilton Rowan Gamble, while the school is a namesake of Alexander Hamilton, the early American statesman.
