In 1847, Ebenezer Walden sold a portion of "Walden Hill" to Joseph Masten, Mayor of Buffalo and judge of the Superior Court. This portion included the Ansley Wilcox House.

Masten resided here from 1847 to 1863. At this time the house still faced west, toward what had been the old parade ground. Sometime in the 1850s or 1860s, the front portico of the house was either moved or rebuilt on he much more fashionable Delaware Avenue side.
