Definition and etymology of "criminy"?

Curious about this mild expletive (along the lines of “egad” and “drat”) which people use from time to time: “criminy” ( spelling may not be correct). Does anyone know the definition and/or root of this word? It doesn’t show up in any dictionary I’ve checked.

Off the subject:
I think “egad!” is a modification of “ye gods!”

My favorite almost-blasphemous expression has got to be:
’s blood!
which is a modification of “God’s blood!”

Or the archaic, “Zounds!”, short for God’s Wounds.

So the word “heck” is a euphie for “hell”, right?

Q

“By jiminy” is an attempt to not blaspheme Castor and Pollux.

Thanks for all of the information. My question has been answered expeditiously and I have no reason to doubt the accuracy! Zounds! You have satisfied a great curiosity.
