19th-Century English Staffordshire China

Q. I’ve had this set of deep blue-black and white dishes for over 50 years. There are eight dinner plates, eight breakfast plates, eight cups (without handles) and deep saucers, two square vegetable serving dishes, one deep round serving bowl, a teapot, creamer, and sugar bowl with lid. They are all in excellent condition. The design shows a church in a landscape. The mark on the back reads “Abbey” and “W. Adams & Sons.” I’d appreciate any information.
