History
What eventually became Rochester was originally a Lenape village called Sawcunk. The area was settled in 1799 in what was then the American frontier by white settlers and was known as East Bridgewater, Fairport, and Beaver Point. The borough adopted the name Rochester in 1834 when a local businessman who did regular business in Pittsburgh decided to christen his home with the name Rochester so he could have a unique name to stamp his goods; the borough was officially incorporated as such in 1849.
Many of the streets that run through Rochester today had different names based on wild animals.

Architectural summaries often privilege surviving fabric and can understate demolished phases, contested use or displaced communities. The lead is largely declarative, so disagreement and counter-evidence require a deliberate search beyond the opening account. Authority statements aid reconciliation but still require their own references, qualifiers and ranks to be checked.
