It’s not so far out. English is a mix of German (through the Saxons), French (through the Normans), Latin (through language of the scholars and the Church), and Scandinavian (through the Danes who settled in Eastern England, and indirectly through the Normans).
One of my least favorite dates is 1066.
Dang Normans.
It is a mix of all those, and more, but German is first.
