While researching my Italian heritage in Trentino, Italy, I discovered quite by chance that a variation of the Schneider name appears in that area. As this region is near the Austrian border and has some German speakers nearby, this is not really much of a surprise. What is interesting is that, at some point in the late 1600s/early 1700s, the surname "Snaider" was apparently changed to "Pederzolli". Can anyone shed some light on the geographic origins of the "Snaider" spelling?
