This coat of arms is reported in the "Heraldry of the Royal Families of Europe", by Jiri Louda and Michael Maclagan, Clarkson N. Potter, Inc. Publishers, New York, 1981, p216, table 109. While these arms are virtually the same as the city of Mainz, it is a common heraldic law that identical arms are allowed when the bearers are of different nations, but within a nation they are not (see for England,
Warbelton v Gorges and
Scrope v Grosvenor). However, Wikipedia reports a different set of arms for the family at the article on
