Is there any chance of a relation between Judith "de Castro"and the St.Croix family that spelled their name DaCosta/DeCosta? An appendix in the book "Robert Skeoch: Cruzan Planter" by Irene Armstrong contains a story about a Spanish Count DaCosta who renounced his Catholic heritage and became a Jew when the King of Spain would not forgive him for marrying a Jewish woman. The Count took up residence in Portugal and is said to have been progenitor of the Jewish DaCostas.
