I need some mild Irish curse words/phrases for a character to say. They need to express surprise or exasperation and be about on the level with 'what the heck,' 'geez,' and 'criminy.' I thought of using 'faith and begorrah,' but that sounds a little stereotypical. Also, the phrases don't have to be current; they can date back as far as 1910 or so.
I could also use some similar American slang from the 1920s.
