John: I've never heard of a community or church with this name being in Monroe Co., but that doesn't necessarily mean it didn't exist. Many little churches disbanded and changed their names. A computer search of Arrowheads to Aerojets has no St. Matrinus, but did have a St. Martinus Pp. 393-394: " Largely because of the interest in the parochial schools, references to Sunday Schools in Kirchenverein literature are exceedingly rare. Pastor Rieger, at Highland in 1843, conducted a Sunday School attended by from twenty to twenty-five 394 Protestant and Catholic children. He considered this the most promising part of his labors. In 1848 Pastor Binner had established similar schools at Waterloo and at St. Martinus where, on Sunday afternoons, about twenty children attended with their parents." This is the only "hit". Now I'm curious. Pat, have you ever heard of St. Matrinus or St. Martinus village or church in Monroe Co.? Janet
