Philip I of Piedmont
Philip I, known as Philip of Savoy  (1278 – September 25, 1334) was the lord of Piedmont from 1282 until his death and prince of Achaea between 1301 and 1307.
He was the son of Thomas III of Piedmont and Guyonne de Châlon.
Philip's first marriage was celebrated in Rome on February 12, 1301 to Isabella of Villehardouin, Princess of Achaea.
By that marriage, he became Prince of Achaea, though he had already been lord of Piedmont by inheritance from his father in 1282.
He was, however, an authoritative prince and this put him at odds with the baronage of his realm.
He tried to placate the barons of Morea, but was forced to accept a parliament in 1304.
The Greek archonts from Skorta revolted in 1302.
In 1307, King Charles II of Naples, the suzerain of Achaea, confiscated the principality and gave it to his son, Prince Philip I of Taranto.
In 1312, Philip married Catherine de la Tour du Pin (died 1337), daughter of Humbert
I of Viennois and had issue:

Thomas III of Piedmont
Count Thomas III (c. 1246 – 16 May 1282), called "Thomas of Savoy" or "de Savoie", was the lord of Piedmont and a claimant to the county of Savoy from 1268.
He was the eldest son of Thomas II of Savoy and Beatrice di Fieschi, niece of Pope Innocent IV.
Upon the death of his father, Thomas became Count in his paternal estates in Piedmont.
When his first cousin Boniface, Count of Savoy died in 1263, the 15-year-old Thomas regarded himself as the successor of the deceased, and claimed the county and the headship of the house.
However, his late father's younger brother Peter II, Count of Savoy, a sonless nobleman who had resided in England for much of his life, was recognized as count.
After Peter's death in 1268, Thomas continued his claim although Philip of Savoy, archbishop of Lyon, the youngest surviving brother of his father and also sonless, succeeded in the county and was recognized.
Thomas III, as he was the eldest son and heir of Thomas II, felt an injustice in being surpassed by younger brothers of his father, and claimed unsuccessfully Savoy from his uncles.
Thomas III married in 1274 to Guia of Burgundy, the stepdaughter of his uncle
Philip I of Savoy
and they had five children:
Philip and Thomas were in dispute much of their reigns 1268–82.
Thomas' marriage was a rather unsuccessful attempt to patch up things and get Philip to recognize hims as the successor in Savoy, which would have belonged to Thomas, him being the eldest son of Thomas II and thus the founder of the genealogically senior line of the House of Savoy.
Philip’s will charged his niece Eleanor of Provence and her son King Edward I of England with the inheritance of Savoy.
Thomas III was fatally wounded in a border dispute with Humbert I of Viennois in 1282.
