Heinrich XXIV was born at Greiz, Reuss Elder Line, only son of Heinrich XXII, Prince Reuss of Greiz (1846–1902), (son of Heinrich XX, Prince Reuss of Greiz and Princess Caroline of Hesse-Homburg) and his wife, Princess Ida of Schaumburg-Lippe (1852–1891), (daughter of Adolf I, Prince of Schaumburg-Lippe and Princess Hermine of Waldeck-Pyrmont).
Caroline was a daughter of the reigning Heinrich XXII, Prince Reuss of Greiz by his wife Princess Ida, daughter of Adolf I, Prince of Schaumburg-Lippe.
The Reuss Elder Line died out with the death of the childless Heinrich XXIV in 1927, after which its claims were passed to the younger line.
