Just working this genealogia as the first few names in it are direct for me (namely Catarina Pires de Quintal, daughter of Pedro Lopes de Quintal). Further on I came across Nuno Goncalves Cardoso who married (it says) Catarina de Roz daughter of Nicolau de Roz and Isaura Perestrello. I've never seen the name Roz before - and it does not appear to be an abbreviation for Rodrigues as I initially thought. It also says they are from the Titulo de Henriques Alemao- another one I am not familiar with. Just thought I'd see if anyone can shed any more light on either of these names. Cece
