Aldonza de Villasenor Davalos e Hijar/ Juan Dosal de Lamadrid

I have an Aldonsa Villasenor y Davalos (AFN:1N81-0PP) married to Juan Dosal de Lamadrid (AFN:1N81-0NH), Teniente General de la Sierra de Tepeji y Sombrete, Alcalde Mayor de Charcas. Her parents were Gonzalo de Villasenor (AFN:1N81-ZS6)and Aldonza Avalos e Hijar (AFN:1N81-ZTD). Her maternal grandparents were Diego Lopes de Saavedra and Francisca Fernandez de Hijar- through her materal line she descends from the Conquistador, Juan Fernandez de Hijar. The Fernandez de Hijar family are descendientes varonia del Rey don Jaime de Aragon. Through her paternal line she descends from Isabel de Alvarado, niece of Adelandado Pedro de Alvarado, also a Conquistador. Her paternal grandfather was Alfonso de Bracamonte, son of Alvaro de Bracamonte and Beatriz de Alvarado, so she is also known as Aldonsa Villasenor Davalos de Bracamonte e Hijar. Was wondering how I could find out if this is her first or second marriage?

kind regards,
