Samuel De Champlain, an important figure in French History. An interesting figure...He was an amazing explorer, geographer, navigator, a soldier and etc...He established quite a few land-scapes in his voyages. One being in The New colony of France - The City of Quebec. During his voyages, he traveled through many seas, including; the northern sea, Celtic Sea (France to Spain. first voyage), and Lac Attigouautau - fresh water.
He even had the "Atlantic Ocean" temporarily be named after him - The Champlain Sea. 

I hope this helps :) Lets hope I didnt miss any seas.
