Westmoreland County Historical Society


Welcome to our website! Whether Westmoreland County is your home, your ancestors' home, or a place you would like to visit, let the Star guide you. 



The genealogy & regional history Calvin Pollins Research Library is closed and will re-open in 2019 in the new Westmoreland History Education Center at Historic Hanna's Town. The exact date of re-opening depends on construction progress -- currently estimated to finish in mid-February, 2019. Then placement of shelving units, books, and other resources can begin. You may still contract for research services. For additional information, call 724-532-1935 ext. 210 or visit:

Star of the West was a title given to Westmoreland County by 18th century German pioneers who regarded it as a "stella" or star as they traveled from eastern Pennsylvania through this region and toward western territories. The 5-pointed star also represents the five counties that were carved from Westmoreland's original boundaries - Allegheny, Fayette, Greene, Washington, and Westmoreland. This Star reflects our mission to provide a guide through history to a greater understanding of the present and a clearer path to the future.
