Does anyone know of a link between Thord Gellir of Iceland and the Gellers of the Cologne area?

Question

I have documentation back to 1600 for Gellers near Koln and Aachen. But no farther. Sagas indicate Gellir Eyolfsson went to Cologne Univ.

Answer 1

Do you mean Gellir, son of Thorkel  Eyjolfsson?  Wouldn't he be called Gellir Thorkelsson?
