Ada (?)

     Ada was born. Ada married Humphrey (?). It has been assumed that Humphrey was Ada's husband. It is known that Ada is the mother of Alexander and that he [Alexander] was raised by his uncle, Roger of Salisbury. It is also known that Roger had a brother Humphrey. Thus, Humphrey could be the husband of Ada or if Roger had other brothers, then any of the brothers could be a possible husband of Ada, the mother of Alexander.
