Hammersley Street
From the Larkin Street page:

William Larkin was a town assessor in 1846, and helped A.A. Bird build South Hall - the second building on the UW-Madison campus - in 1854-55. In 1891 his heirs sold the farm to E.C. Hammersley.

Hammersley then entered into a partnership with John Olin and in 1916 they sold the farm to the Owen Park Land Co. Within a decade the farmland was platted and houses were erected.
