Quite, though I'd suspect something a little older, maybe
something closer to harjamanniz.

I think *ch- is what I was thinking of.

Well, there do appear to be Celtic cognates of *harjaz, so perhaps
Caesar got hold of a Celtic word of some sort.

Naturally, misapplied to sore throated and by now pharyngitic
Germans who could not enunciate a sensible rebuttal to 
Caesar's improper appelation!

Yes, I've come across that as well.

Lancaster, actually. ;)))

Seriously, according to the Font of All Knowledge, Pennsylvania
Germans came mostly from Alsace, Palatinate and Switzerland.
