I know how the sailors pronounced 'oud' ; that is the way how I (born in The Hague) pronounced it for a long time, lol: 'aht'.
No, I did not say that. I have once said, that the Gertmann were from Frisian origine and that it was a misinterpretation of Ottema to rank them as Germans. By the way it was the original idea of Ottema to rank the Gertmanna as Frisians, but he changed his view. OLB states that the Gertmanna kept their Frisian customs.
