As the eldest surviving son, Franz Philipp inherited the Göllersdorf estate (a Lower Austrian lordship acquired in 1710 from the last Count of Puchheim, the Bishop of Wiener Neustadt) and Weyerburg estates (another Lower Austrian lordship acquired in 1715) and Palais Schönborn-Batthyány in Vienna (which had been acquired in 1740 from the widow of Count Adam Batthyány).

[7] All were acquired by his great-grandfather's brother, Friedrich Karl von Schönborn, the Prince-Bishop of Würzburg and Bamberg who served as Vice-Chancellor of the Holy Roman Empire.

[8] Franz Philipp is considered the founder of the Austrian branch of the Schönborn family, which became known as von Schönborn-Buchheim.

He was succeeded in his title by his eldest son, Erwein, who resigned his rights to his brother, Karl, in 1844.

[9] Through his daughter Sophie, he was a grandfather of Philipp Franz Erwein Theodor, 3rd Prince of Leyen-Hohengeroldseck (1819–1882), who married Princess Adelheid Karoline von Thurn und Taxis (a direct descendant of Alexander Ferdinand, 3rd Prince of Thurn and Taxis).
