Are the French descended from Gauls, Germans and Vikings?

Most people living in France are descendants of Gauls, and there are Italians, sarma, bretons, aquitaine (Basques), Iberians, Greeks and others in the south. Germans (such as Franks and Burgundy) who came to France at the end of the Roman Empire, mixed-race Moors and Saracens, and Vikings who lived in Normandy in the 9th century. The word "France" comes from the Frankish kingdom where Franks live. Franks are Germanic tribes, and entered Rome Gaul at the end of the Roman Empire. There were a large number of Celtic and Germanic immigrants in some areas before the Frankish Kingdom, such as Brittany (Celtic) and Alsace and Saxon (Germanic). The languages and customs in these areas are still very different today.
