Detailed history of Schallenberg/Schellenberg
from Martin J. Shallenberger's book "Shallenbergers of Echo Mountain, Vol. 1"

It appears that the Schallenbergers, Schollenbergers and Sollenbergers (commonly misspelled Sullenberger) came from the Greater German Empire, specifically Prussia, Bavaria, and Switzerland.

Sollenberger may have come from a Sollen Tahl (Sollen Valley) in Eastern Switzerland.

	This Shallenberger crest is found in Whitley's book and bares the enscription "Gift: Mrs. Paul L. Newmeyer, Nov. 1961". She further writes, "The above shield of Heinrich Schellenberger who was Aide-de-camp to Hans Von Halwyn, and who was present with the General at the famous Council of Constance, held by the Pope at Constance about 1480. The book recording the work of the Council was printed or rather written in the German language, hence the German way of spelling."
Gold shield charged with a blue pointed arch, having at the base a golden harness bell, resting on a green triple peaked mountain.

	(Right) In the memorial chapel, built at the site of the Battle of Sempach, the names and coats-of-arms of the knights who fell in the battle are painted on the chapel walls. One of the shields of knights from Swabia is for the Ritter (knight) Heinrich von Schellenberg. See Martin's history at top of page.
	(Left) The main databases that have been made of family coat of arms shows this as the Schellenberger shield. Researchers investigate a name and catalog the "oldest mention of a specific name and the first one of that name that received a coat of arms". Take it for what it is worth.

Also there is a Schellenberg castle in northern Liechtenstein. Schellenberg is now the name of one of the communes (states) of Liechtenstein. The flag of that commune shown here is based on a description in Walter Kranz (ed.) The Principality of Liechtenstein: A Documentary Handbook, 5th edition, Vaduz, 1981: "Divided horizontally in four - alternately black and gold." The arms are gold with a black fortress wall. At the top appears a black stripe. The colours represent the nobles of Schellenberg, and the fortress wall their castle. The arms of Schellenberg were adopted on 28 March, 1940.
