Preliminary note: Rua was written either Rua or Ruas - for the same family, and sometiomes for the same individual. In PA( título Freires) I found 2 Catarinas da Rua ) mother and daughter) possibily closely linked to Catarina da Rua. m. A, Gonçalves (parents of Violante Soares m. Marcos Gil Caldeira) . So (except Belchir de Moura baptism the dates are hypothetical) we have: 1. Belchior de Moura bap. 1530 m. 155...Marquesa de S.Paio, they had: 2. Gaspar de Moura m. Catarina Ruas (m. 157...) dau of Diogo Furtado de Mendonça and Ana Lopes, and they had: 2. Catarina Rua. m. ( 159.... 1600) ( João de Mendonça Freire) As Rua or Ruas is not a common a name at all there is a strong possibility that these 2 Catarinas and the other that we know are closely reltaed. Moreover they have the same name and surname. Miguel de Castro Henriques
