I was under the impression that I had a fair share of knowledge of the Germanic languages that are and were spoken throughout history, and then this early split of of the English language pops up which I had never heard of, Yola.
It's great to look at it, and how it continued until mid-19th century. It still as ich for 'I', thou for 'you', no great vowel shift, loss of word final dentals, and voicing of word initial fricatives. It actually looks a bit as if Middle-English was influenced by southern Dutch.
And then there's some lovely Irish influences too like here:
loyale dwellerès na Baronie Forthe
Loyal Dwellers OF THE Barony of Forthe.
na is the Irish genitive of the definite article feminine.
So now I do wonder, who did know about this one?
