The Przewodnik Handlowy was published in Buffalo in 1906. The book contains genealogically-relevant paid ads, for which information was supplied by the advertiser. In most cases, information includes place and date of birth, name of spouse and year of marriage, names of children, and the organizations or parish to which the family belonged. The entire album is now available for browsing and searching online. Alternatively, we offer a database of names found in the Przewodnik Handlowy. A complete English translation of this text is available here.
