Edward ap Howel would be the next in line. He is identified as "of Llwyn-Onn", and his wife is Margaret Wyle of Bersham.
Bersham was a border area along Wat's Dyke. Llwyn-Onn of Llanfair was to the west, and Llywn-Onn of Wrexham was to the east. It must have been along these roads that the family managed to survive both the Anglo-Saxon colonization, and the gradual Norman annexation.
The above figure shows the time analysis for these generations, Howel (JM-1) and Edward (JN-1). Both the wives were named Margaret, and this name becomes the most common name among my JONES family tree.
