Wigmund of Mercia
From Infogalactic: the planetary knowledge core
Wigmund may have briefly reigned in Mercia in about 840, in succession to his father, Wiglaf of Mercia. He may, on the other hand, have predeceased his father and never been anything more than a co-ruler with him. He was himself the father of Wigstan who later declined kingship, he married Ælfflæd, daughter of Ceolwulf I which leads people to believe that Ceolwulf the II was a descendant of Wigmund and the last of the original Mercian dynasty.
