The photo is believed to be of the Coatesville baseball team, circa 1895. Coatesville resident Edward "Eddie" Warren (1876-1956; son of Zimri Warren and Abigail Layton Figg) is seated in the middle row, second from left (holding the catcher's mask). Brief History of Coatesville by Joe H. Davidson (1966) has a section on Coatesville baseball and mentions the Coatesville Bluz, a team which was said to have been organized between 1906-1916 and managed by Bill McAninch. So the team in this photo may be the Coatesville Bluz, or it may be a predecessor to that team.
