 Two of Humbert's sons were commendatory abbots at the Abbey of St. Maurice, Agaunum, on the River Rhone east of Lake Geneva, and Saint Maurice is still the patron of the House of Savoy.Humbert's son, Otto of Savoy succeeded to the title in 1051 after the death of his elder brother Amadeus I of Savoy and married the Marchioness Adelaide of Turin, passing the Marquessate of Susa, with the towns of Turin and Pinerolo, into the House of Savoy's possession.This diplomatic skill caused the great powers such as France, England, and Spain to take the counts' opinions into account.
