# Rostraver Township, Pennsylvania

## History

Rostraver Township is in the southwestern corner of Westmoreland County and is the location of the Household No. 1 Site, which was once occupied by a Monongahela village. It is listed on the National Register of Historic Places.
The name of the township has been traced back to Rostrevor, a seaside community in County Down, now in Northern Ireland. It is known that some of the early settlers, such as the McClains, came from County Down so it is surmised that they probably named their new community out of affection for the native village and spelled it phonetically as Rostraver Unfortunately, they neglected to leave to posterity any record of having done so.
