Origin of name Locust tree

Locust Street appears in the 1830 map of Jean Barbeau and Lewis Keyon, intersecting Chesnut Street (today Chatham Square).[1] This suggests it is named for the locust tree, perhaps the black locust (Robinia pseudoacacia) or the honey locust (Gleditsia triacanthos), both of which are native to western Pennsylvania.[2][3]
