Family Facts: Heraldry
According to Wilhelm Mauer who was a Speidel family researcher from Tübingen, Germany, there were "many, many Coats-of-Arms granted to members of the Speidel family during the Middle Ages. Often the same Coat-of-Arms was granted to different members of the same family, although some changes were made, as well as changes in color."
Johann Siebmacher's "Grosses und Allgemeines Wappenbuch", a very old 35 volume set of books detailing the armorial collection of German nobility, shows some of the Coats-of-Arms granted to members of the Speidel family.
Speidel Coat-of-Arms Granted to Ludwig Speidel by Emperor Frederick III, dated at Linz, March 20, 1467. The original is in Vienna, Austria.
Speidel Coat-of-Arms Also granted to Ludwig Speidel by Emperor Frederick III, dated at Linz, March 20, 1467. The original is in Vienna, Austria. A description is as follows:
Coat-of-Arms: in red, three iron colored wedges
Helmet: two arms dressed in red, a gold seal raised Decken: red, gold
Speidel Coat-of-Arms Granted to Johan Jakob Speidel, representative of the Emperor and ambassador at the Council in Ragensburg 1666.
Speidel Coat-of-Arms Granted to a Speidel at Neckarsulum in Würtemberg, served by servants and in ownership of land.
Speidel Coat-of-Arma Shown on the covers of "Beiträge zur Geschichte der Familie Speidel - Die Balinger Speidel" and "Beiträge zur Geschichte der Familie Speidel - Der Holzgerlinger Müllerzweig der Speidel" both by Wilhelm Mauer. I am not sure who the Coat-of-Arms was granted to but it is very similar to the Arms granted to Johann Jakob Speidel.
