Help Identify Pottery Crocks/Jugs Please

I have four older crock jugs that I need help identifying and finding value. The one is relatively easy (Western Stoneware)but the others are not as easy. There are two with star marks. 1-two gal. jug and 1- three gal. jug, the final and most intriguing one is the 2 gal. Heart stamped jug. Any help is greatly appreciated.
