Apparently there was a community known as Blue Ball, for the nearby ball clay deposits. But the local post office received the name West Decatur, an unincorporated community in the southwest corner of Boggs Township, Clearfield County. West Decatur lies along the old Philipsburg and Susquehanna Turnpike, which was part of a through route between Philadelphia and Erie, and is thus now called Old Erie Pike. The community was also on the Clearfield Branch of the Pennsylvania Railroad, opened by the Tyrone and Clearfield Railway in mid-1868 from Philipsburg to Blue Ball, and extended to Clearfield in 1869.

This is apparently where Percy and his father Rudolph were born. It should not be confused with Blue Ball an unincorporated community in Lancaster County, PA.4647
