With the exception of African slaves, is everybody throughout the North American Colonies of British Isles descent?

By North American Colonies, I mean from Florida (initially Spanish but later British) to Newfoundland to Alaska and down to California (also owned by Spain, but the British claimed it).

English, Scottish, Welsh and Irish are all the same people and fought in the same army. These people make up the demographics of the North American Colonies.

Although the "Germans" (Hessians as they're often called) and Dutch (whom founded New York but we gladly stole it from them) were already in the Colonies in moderation, and the Irish have always been British... where the bloody hell did these bloody Italians/Scandinavians/Russians/Jews/Minorities come from?

Bloody Italians! Bloody Scandinavians! Bloody Russians! Bloody Jews... BLOODY MINORITIES!!!
