Most are derived form Latin and various Norse/Pict languages at the time. There are some specific words we have from French, usually later (renaissance) period; Toilet, Parliament, for example.
Not only from the Renaissance. In fact, as far as I know, most of the French-derived words in English come from the Norman Conquest, many centuries before the Renaissance.
When we say French-derived words in English are a large proportion, we don't mean those very odd and late words like Parliament and toilet, but we mean words that are so entrenched in the English language that usually natives don't recognize as foreign words at all!
Examples:
crown, state, reign, realm, court, army, peace, battle, spy, aid, challenge, chance, change, enemy, danger, escape, guard, force, judge, just, damage, case, marry, marriage, oust, prove, false, service, virgin, angel, pray, duty, virtue, order, save, blame, grace, cruel, chaste, desire, beef, pork, bacon, sauce, boil, roast, toast, soup, brace, couple, dice, cater, size, art, beauty, colour, image, paint, tower, palace, castle, air, age, arrive, beast, feeble, large, letter, manner, cry, debt, matter, place, point, price, reason, turn, use
Sure, many of those words come ultimately from Latin, but they made their way into English via French (even with the "French" form: note "chance", which comes from Latin "cadentia").
Cheers,
