Ok - that gives us an even earlier date. Coursin Street was put in prior to 1881. Coursin Street Methodist Episcopal Church North built a large stone structure on Coursin St starting 1879 and finishing in 1881. My Aunt Luella Taylor was the organist there for years, and was followed by Ruth Richards whom many of you would also know as the librarian at Carnegie Library of McKeesport. If memory serves me correctly. Carnegie built the Braddock Library as his first and McKeesport was given the second library. Marc M. G. Stauffer
