ERUDIA, TEXAS. Erudia, ten miles west of McKinney in extreme western Collin County, was probably named by settler William Allen, after a character in his Erudia, the Foreign Missionary to Our World (1890). Erudia got a post office in 1895; in 1902 it was closed and mail was routed through Frisco. After the early 1900s Erudia disappeared from county maps.
