His Hebrew name was Yedidia. The surname appears in documents by two spellings, Fächer and Fecher. He was born in Debiça, Poland (formerly Dembitz). He was also the father of Ignácz Chaim Fächer, who is buried in the Jewish cemetery in Jelsava, Slovakia. The inscription on Ignácz's headstone includes Yedidia's name. That he came from Dembitz is information that was confirmed by descendants of both Ignácz and Daniel Jozsef. It is considered reliable because these descendants live on different continents and have never been in contact with one another, yet both were told the same information.
