Yeah, Americans only knew of them from their dealings with France. As Wikipedia puts it
Thomas Jefferson had "potatoes served in the French manner" at a White House dinner in 1802.[13][14] The expression "french fried potatoes" first occurred in print in English in the 1856 work Cookery for Maids of All Work by E. Warren: "French Fried Potatoes. – Cut new potatoes in thin slices, put them in boiling fat, and a little salt; fry both sides of a light golden brown colour; drain."
This doesn't sound like the modern chips at all. More like actual potato chips.
