de Frias - NS Rosario, Lagoa

[Carlos Melo]

Hi,

My 11th great-grandmother, Maria de Frias, was the daughter of Afonso de Oliveira and Isabel de Frias, according to her marriage record in NS Rosario, Lagoa, on November 1, 1594:

According to multiple family trees in Geneanet and other platforms, her maternal grandparents, i.e., Isabel de Frias' parents, were Goncalo Vaz Pimentel and Ana de Frias, but I cannot find any evidence of this kinship.

Does anyone share this ancestor and have this evidence?

Thanks! 

Carlos
