Old "Polish" Phrases used by family (in US)

These phrases are supposed to be Polish...things my grandmother knew that she learned from her in-laws.

Not sure on spelling, so if anyone can spell them right, that'd be great...and if anyone knows if they're what (or not what) I've been told they are, then by all means please say something!

Okay...pronunciation is by Midwest-US English standards (if that helps)
"zy-own-ts" for rabbit
"jeff-tina" for little girl
"ay Jezus coo-ha-knee"...something about Jesus

Thanks.

Zając; dziewczyna; O Jezus kochany!

nitpickingly...a zając is a hare; a rabbit is a królik. Except for the jackrabbit of the Wild West which, as I have been told, is America's only true hare.
