his simplified genealogy examines the main line and northern kingdom
of Powys. In the 9th century Powys was joined with the kingdom of
Gwynedd.
Powys later broke from Gwynedd, then split into northern and southern
kingdoms in the mid 12th century. The northern kingdom was ruled by
Madog, while the southern kingdom was ruled by his brother Gruffydd,
sons of Maredudd ap
Bleddyn. To simplify the presentation here, the line of
descent has been placed in the center of the page and is not
necessarily an indication of birth order. (Kings and princes are
shown in capital letters)
