This crest is on the plaque of the "Steiner-Quarter". It's a little
part of Steinen.
This crest is probably the only official Holdener family crest in this
century, as all known Holdeners have this crest though we have different
"fathers".
This crest is from Uli Holdener, which was engraved on the bell to Steinen
(Canton Schwyz, Switzerland).
This crest is apparently an imported Holdener family crest in Mr. Fassbind's
book "History of religion", band 1, without indication of sources.
Crests 1, 2 and 3 come from the "Schwyzer-Wappenbuch", a book about family crests in Canton Schwyz. Crest 4 is found in the "Historisch Biographischen Lexikon der Schweiz", an encyclopaedia.
