Does anybody have Primary sources or, a birth year for either Sibeud Tivoley or his children listed in biography?

Question

Sibeud Tivoley (Seigneur de Brenieu en Vivarais)(Died after 1566) has no birthdate for his profile nor, are there any for his children listed in his biography with Marguerite (Pole) de Le Pole (before 1525) illegitimate daughter of Richard (Pole) de Le Pole (1480-1525) (White Rose). Without birthdates or, death dates either I cannot create profile with sources for his children.
