Hoi Margreet, it's possible that his ancestors are from Wien.
A tailor is in Jiddish a Shnayder, Sneijder in Dutch, see my point, I think that somebody have made a mistake with the Jiddish/Dutch translation, and translated it to Schnitsler, as is named in the original, Ashkenazi documents, the problem is that hebrew and Jiddihs use the same alphabeth but the phrase is different.
