[1] She was the only legitimate child of Peter II, Count of Savoy, but did not inherit the county, which passed instead to her uncle.

He was eventually succeeded by Beatrice's older daughter Anne and her husband Humbert, with future dauphins descending from their marriage.

Following the death of her son, Beatrice left for Taninges with his remains, laying them to rest there and praying for his soul in the monastery she founded, Mélan.

[7] Beatrice arranged a marriage for stepdaughter Constance of Béarn to Aymon II of Geneva, a relative through her grandmother.

In 1294, she transferred her lands between Seyssel and Freiburg to her cousin Count Amadeus V. In 1296, she gave up her title as Dame of Faucigny to her son-in-law Humbert, for the benefit of one of his sons, reserving the usufruct for herself.

Her various alliances with relatives and clerics in Geneva and the sharing out of her inheritance during and after her life, led to conflicts amongst her descendants for generations.
