Osborn estate
Osborn Road remembers the Osborn country place. The remaining institutional campus and marshland are what was not sold as house lots. Streets against that edge sit on the cut-down estate.
The Osborn name stayed on the land as a retirement community and as Marshlands Conservancy. The residential streets are the part that went to the assessor roll.
