As was said earlier there had been Dutch colonies, but these had been taken ove by the British by this time. There were some Germans serving with the British but not as separate units. Both the French & British had foreigners serving in their Armed forces but not in independent units. Many of the colonists were of various european dissent, including Swedes, Danes, Germans & Dutch. Scotts & Irish were also considered foreign and may have served on either side.
That's right, no units of other nationalities as such, but as said, loads of other national descent types in some of the colonies, especially Duch and other northern Europeans still being the majority in some areas, although now subjects of Britain, look at some of the names in the Colony of New York at the time.
There were certainly Irish serving in French regiments in Canada, I'd be interested to hear of any Scots or Irish living in British colonies who (willingly) defected to the French, now that would be a 'ripping yarn'

Piero, I agree re the earlier stuff involving the Swedes being interesting, though I still think the mid eighteenth century has the edge on it.
