Named, believe it or not, for a breed of chicken: the Plymouth Rock, to be exact. Plymouth Street was laid out on 1905’s Orpington tract – Orpington being another chicken breed – which was part of the Inglewood Poultry Colony, a place designed for individual property owners to set up their own coops and raise (and sell) their own chickens and eggs. The colony, brainchild of newspaper columnist and “leading poultry fancier” Mabelle Burbridge, was expanded westward in 1906-1908 with three additional chicken-themed avenues: Wyandotte, Leghorn, and Orpington itself. Alas, they ran out of cluck, as it were, and were coopted into Inglewood Avenue, Beach Avenue, and Glenway Drive, respectively.
