I have Isabel Gil Moniz married to B, Perestrello in my lineage. It does not list her parents. However, I do also have Isabel Moniz whose father was Goncalo Moniz Barreto and her mother was Maria Fernandes Sanches. She was not married to Bartolomeu Perestrello. She was married to Christovan Martins. I also have another Isabel Moniz. If you like more information on the last one, I can provide that to you. Sorry I could not help with the first one's parents.
