Ackshly, many English words derive from Old English - a lot of our very basic words do. Hand, foot, mother, father, son, daughter, wife, man, life, bone, fire, lord, lady, good, evil, sun, moon, bird....the list goes on and on.
The incursion of French happened over several centuries, which explains why we have jaunty, gentle and genteel all from the French word "gentil" re-entering the language at several different times. The latest and largest incursion happened in 1066, when William of Normandy defeated Harold Godwinson at the Battle of Hastings and began a hostile takeover of England. I direct you to a lovely little passage in "Ivanhoe", where a swineherd and a jester are discussing language - or, more properly, why a bovine is a good Saxon cow ("cu") on the hoof, but Norman beef ("boeuf") on the table. Similarly the English pig becomes French pork and the English sheep, French mutton.
Perhaps someone else has some scholarly info on accents. Canajans have 'em too.
