Also, at digital.library.pitt.edu/maps/warantee,
you'll find a digital version of the Warrantee Atlas of Allegheny County, 1914. The atlas depicts
the original land grants that settlers of present-day Allegheny County received from the
Commonwealth after William Penn and his descendants vested the land to the legislature.
The Warrantee Atlas is ordered by township, cities, boroughs, and river beds and islands.
It includes the name of the individual who received the grant, the date the land was warranted
and surveyed, property dimensions, patent information, and sometimes the name the property was
given by the title owner.
