Northern England’s English had Nordic influences. Southern England and Normandy had French influences.
Old English had many dialects.
The northern Old English dialect used the Old Norse word egges for eggs. It became the standard word for eggs throughout England. The southern Old English dialect word was eyren. See Kentish dialect. See William Caxton.
“Caxton is credited with standardising the English language through printing—that is, homogenising regional dialects.” (Wikipedia entry on William Caxton)
