Philip Joseph, Prince of Salm-Kyrburg

Philip Joseph, Prince of Salm-Kyrburg (1709-1779) was the first prince of Salm-Kyrburg, from 1743 to 1779. He was the second son of Hendrik Gabriel Joseph, regent of Salm-Kyrburg from 1696 to 1716, and his wife Maria Theresia of Croÿ. He had an elder brother, Johan, and a sister, Henriëtte Therese Norbertine (who married prince Maximiliaan Emanuel of Hornes, who already had two daughters from a previous marriage, the eldest of whom later married Philip Joseph).

He was the first prince of Salm-Kyrburg. The Wildgraveship and Rhinegraveship left the Salm-Mörchingen family in 1681, who lacked a male successor, and was from then on run for them by regents. Philip Joseph reigned with his brother Johan from 1716. When Salm-Kyrburg again arose, this time as a princedom, Philip Joseph became its first prince.

He married in 1742 princess Maria Theresa of Hornes, who was made her father's sole heir in 1794, with his titles and country estates thus passing to the princes of Salm-Kyburg. Emanuel's other daughter, princess Elisabeth Philippine Claude of Hornes, widow of sovereign Gustaaf Adolf of Stolberg-Gedern and mother of Charles Edward Stuart's wife Louise, agreed to this without protest.

Philip Joseph and Maria Theresa had 10 children, including one pair of twins:
* Marie Maximiliane Louise (1744-1790), married Jean Bretagne Charles de La Trémoille, duke of Thouars
* Frederik (1745-1794), later prince of Salm-Kyrburg
* Auguste Friederike Wilhelmine (1747-1822), married duke Anne-Emanuel de Croÿ
* Karel Augustus (1750)
* Marie Louise (1753-?)
* Lodewijk Joseph Ferdinand (1753-1774)
* Elisabeth Claudine (1756-1757)
* Amalie Zephyrine (1760-1841), married prince Anton Aloysius of Hohenzollern-Sigmaringen
* Karel Albert Hendrik (1761)
* Maurits Gustaaf Adolf (1761-1813), married grafin Christiane of Wartenberg
