The coat of arms of the "Younger Count's Line" (JGL), granted by Prussian count's diploma of 14 October 1861 for Rudolph Maria Bernhard Count of Stillfried-Rattonitz, Grand(e) of Portugal and Count of Alcantara and his marital heirs and descendants (for a document with a detailed description see Rudolph Stillfried, Urkundenbuch von 1869, p. 452 ff, document CCCCLVI).
In addition to the ancestral coat of arms, it includes those of the ancestral families Werder and Schlenz (red field with silver diagonal cross and 4 four-petalled golden roses), Zischwitz and Waltersdorff (blue field, within it a crossbeam nested by 5 blue and 5 red stones) and Walditz von Wernersdorff (in a silver field a right-turned * panther of natural colour, striding on a shield base nested by silver and black lozenges). Above the main shield hovers the golden count's crown set with 9 pearls, the rim of which is adorned with precious stones. From under this crown emerges a purple cloak enclosing the main shield and lined with ermine, as it had already been awarded on 24.5 1794 by Frederick William II to the older count's line of the Freiherrlich von Stillfried's dynasty.(The description of the crest follows, as illustrated)..... The shield holders are taken from the Hohenzollern coat of arms and were granted to Rudolph Stillfried in 1849 by Prince Carl-Anton zu Hohenzollern-Sigmaringen and confirmed in 1859 by King Friedrich Wilhelm IV, " on the right the black, red-armoured, red-crowned and red-crowned Burgrave Nuremberg lion, on the left the Hohenzollern silver, red-crowned Bracke, whose ear is covered by the little customs shield quartered with black and silver. These shield holders stand on a blue, silver-bordered banner, which bears the motto in silver lettering: (*Note: Heraldically, the coats of arms are described as they would be described by the bearer of the coat of arms, who carries the shield with his left arm, seen from behind, if he could see through the coat of arms. The "right-turned panther" seen from behind is therefore depicted correctly (left-turned) in the coat of arms view).
