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.
