Signature

Blanche I (Spanish: Blanca I de Navarra; 6 July 1387^[1] – 1 April 1441) was Queen of Navarre from the death of her father, King Charles III, in 1425 until her own death. She had been Queen of Sicily from 1402 to 1409 by marriage to King Martin I, serving as regent of Sicily from 1404 to 1405 and from 1408 to 1415.

^ Anthony (1931) states that she was the fourth-born daughter of King Charles III of Navarre by Queen Eleanor, and she was preceded by Joan, Maria and Margaret and the two latter died early. Anthony defines Blanche's exact birth date as 6 July 1387 by virtue of contemporary sources.
