 In 1720, the coat of arms of the Washington family was noted as being carved into the stone outside the entrance, possibly because Reverend Lawrence Washington, the great-great grandfather of United States President George Washington, owned the estate in the area that included the church.The shield was later hidden behind stones but was rediscovered in 1885 and protected with a glass case.The church also has stained glass windows bearing the Washington family coat of arms which were removed from Sulgrave Manor, the Washingtons' ancestral home.
