Concerning schools in Chester PA: The school at 15th & Walnut Streets was Martin Elementary School [no longer exists - it was on land now belonging to Widener University.] As to which school was the closest to 431 E. 12th Street. What time frame are we looking for? So many schools have closed over the years. There was a Jeffries Elementary School near Morton Avenue and Melrose, but it was displaced by the construction of Route 95. Jeffries was the school attended by those who lived below the B & O Railroad tracks. The tracks are located between 12th and 13th Streets. Martin School was attended by those living above the tracks. Wetherill Elementary School was on E. 24th Street, near Upland Street. My husband, attended kindergarten at Wetherill, and elementary school at Martin. He attended Smedley Junior High School, on Upland Avenue between 16th and 18th Streets, and graduated from old Chester High School in 1950 [the original building was located on the block bounded by 8th and 9th Streets and Fulton and Barclay.] My husband's parents also attended Chester schools. His father was on the Chester School Board for a number of years. Hope this helps, Elaine Fryer A Delaware County native now living in Erie County
