Question: What is the date of birth of Antonia Of Savoy's father?
Sentence (from "Thomas III of Piedmont"): 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.
Relevant evidence: No
