Avondale is a borough in Chester County Pennsylvania. Avondale is located in the Chester County Charter Index, book 4, page 82; Avondale Borough Dec 1894, but is this our only date of beginning? A great part of our early village was built and has prospered by this time. We must look again. Before incorporation as a borough, Avondale existed as part of New Garden and London Grove townships. Each of these townships having separate origins under William Penn's grants of land in the Proprietorship of Pennsylvania. New Garden was the western part of a grant of land to William Penn's children Latita and William Junior, called the Manner of Stenning. New Garden Township, in which Avondale resides, is the center of the mushroom Agri business in southeastern Pennsylvania with a higher concentration of composting, mushroom growing, packaging and shipping businesses than in any other municipality in the area. It was named for the New Garden Friends Meetinghouse an 18th century brick house of worship of the Religious Society of Friends within its territorial limits. One of the original mushroom farms in the area is now home to a tiny but nationally recognized vineyard and winery, Va La Vineyards.
