Jane, King Miguel may or may not have had Braganza genes in his male line ancestry - we may never know. Of all the children, he was "the apple of his mother's eye" and also unusually good looking in a family where physical beauty was rare, so there were murmurings that he was the child of the queen by a lover. Of course his trouble-maker mother made her share of enemies - some probably happy to spread dirt about her, true or not.
