Johannes Helffrich--Helffrich's Store Stand

Hi,I recently purchased a stone farmhouse in Weisenberg township, Pennsylvania that Ibelieve has roots back to Johannes Helffrich. I have traced the deeds back to Daniel Helffrich and Jacob Helffrich in 1844. I have found some information stating this was the site of a tavern owned by Henry Helffrich in 1813-1815 which was later Helffrich's Store Stand (around 1837). Later it was purchased by Joseph and Catherine Stine, who operated it as a store for many years. The birthplace farmhouse of Rev. Johannes Helffrich in Weisenberg township is about 1/2 a mile behind my house. I would be very grateful for any information, pictures, dates, or names that may have a connection to this house.
