Edward was also the first in his family to use the title "of Van", sometimes spelled "Vann".
The ancestors of Edward were, for many generations, great Lords in East Glamorgan decending from Gwaethfoed, Prince of Cardigan. Although references to time periods in Welsh genealogy are vague, it was know that Gwaethvoed died near the end of the fifth century.
The following pedigree is based on information retrieved from the book, "Limbus Patrum Morganiae et Glamorganiae, Lordships of Morgan and Glamorgan", written by George T. Clark and published in London by Wyman & Sons in 1886.
