Since no reply from Michigoose, I will say that "Jeez o peas" might sound to an oldtimer like "taking the name of the Saviour in vain" and call for either a rebuke or an offer of a less offensive phrase. But "Holy Buckets" also sounds like a euphemism for some forbidden phrase. I have heard some oldtimers say "Goodness Gracious" when they hit their finger with a hammer, and make it clear that it was an inverted form of swearing.
So I guess your daughter might as well pick her own expletives.
Incidentally, I think the word "vain" as used above is related to the German word "wehen" meaning to swear.
