Gertrudes is my Lucy!
I did not expect you to know about Gertrudes! I have searched locally and in all FamilySearch records. I found several records of children, censuses, royal assignments for her husband, but it seems that she appears only as a godmother at weddings and baptized.
I'm always researching. I am in favor of having data sources validating inputs. I will read the PDFs provided by Dr. Anwar Michael Ibrahim and other texts that I have achieved, so as not to be totally clueless.
I downloaded those articles from academia.edu. Look for (Mulçumanos, Ibérica) or (Muslims, Iberian)
This is just to get started!
