Focko

Focko Ukena (1360 or 1370 – 1435) was an East Frisian chieftain (hovetling) who played an important part in the struggle between the Vetkopers and Schieringers in the provinces of Groningen and Friesland. Aside from this he was one of the leading figures in the resistance against the forts of stately authority in East-Frisia of the tom Brok family.
