To ensure male inheritance to the Savoy line, his eldest son Philibert was married to his cousin, the only sister of the deceased young Duke.

Despite the fact that Cyprus and Jerusalem did not bar succession in female line, Philip took those claims and used those titles as well.

His male successors in Savoy also continued to do so, thus giving their ducal title a higher, royal titulary.

His original apanage was the district of Bresse,[2] close to the French and Burgundian border, but it was lost and therefore Philip received his sobriquet "the Landless", or "Lackland".

With Libera Portoneri: With Bona di Romagnano: Philip is an ancestor, through an illegitimate daughter of Honorat II of Savoy, of Joséphine de Beauharnais, first wife of Napoleon.
