What is this building

I walk all over Frankford and find myself passing one interesting building after another. This one is a puzzlement. It looks almost like it has stood on the Old Kings Highway since the days of the stagecoach from Philadelphia. At present it is on the corner of Church and Frankford Avenue. There are some of what looks like similar construction on Adams avenue. Small stone houses are not all that common in this area and I wonder what story this one might tell us.
