town and railroad stop on the Main Line outside Philadelphia, named 1869 by the Pennsylvania Railroad's executives, Welsh, literally "big hill;" it was the name of the estate near Dolgellau, Merionethshire, Wales, that belonged to Rowland Ellis, one of the original Quaker settlers in the region (1686). Before the change the village was known as Humphreysville, after another early Welsh settler. The women's college there was founded in 1885.
