while they were here, they named their place Penn's Grove. Later it was changed to "Penn Grove," and still later, because our mail got confused with that of Pine Grove (the former name of Sebastopol), the U.S. Postoffice Department changed the name to one word—Penngrove." (Harris 1980) Other accounts state that because there was another town with the name of Penn's Grove in New Jersey, this could be a reason as to why the post office changed the name. Others claim that the Woodward family, who came from Pennsylvania, named their property Penn's Grove in honor of their home state. Community development Along with the chicken and egg industry, Penngrove was a source of basalt paving stones, which were used to pave the streets of major cities in the Bay Area, including San Francisco. Harris notes that 200 men were employed at the three major cobblestone quarries at the end of the 19th century, and that quarry scars can still be seen dotting the hills between East Railroad Avenue and Roberts Road. When the Northwestern Pacific Railroad was completed in 1870, the paving stone industry kept Penngrove station busy. After the turn of the century, Penngrove became the "second largest egg and poultry producing area in the country. Only Petaluma outdid this area" (Harris 1980). Apparently, according to The San Francisco Examiner, chickens paid better than gold mines. To this day, many dilapidated chicken houses dot old farms and country roads in the area. Notable landmarks Penngrove Community Church One of the oldest buildings in Penngrove, the old Methodist Episcopal Church was built in 1898 at the corner of Formschlag Lane and Petaluma Hill Road. In 1910, the church was moved on wooden rollers to its present location at 9970 Oak Street. The original building now serves as a fellowship hall, while a newer structure, built in 1955–7, now serves as the main sanctuary. The original structure is still used by Girl Scouts of the USA, Boy Scouts of America, 4-H, and various other community organizations. Penngrove School The first classes were taught in a small building on Peters' Ranch (Harris 1980: 33). In 1876, the first school was built at the southwest corner of Adobe Road and Main Street. It was named the Eagle School after the Eagle Hotel located across Main Street and shown on Thompson's map of Sonoma County (1877). In 1906 after construction of the second
