Hey! I'm from Oregon too! So it shouldn't surprise you that I have no idea either, although I gathered a conclusion from the context. I searched for you, but with no results. At best guess, it's slang for some kind of idiot or heathen. I did find some references to Irish and Scottish families and also to Boontling which is slang from Booneville, California. It's a different spelling that what you proposed and the meaning in Boontling doesn't make much sense in context, but here's the link:

For anyone who read my post but had nothing to add: I asked my husband to pass this question around at work and he struck the leprechaun's gold... A co-worker's wife is Irish and her mother is from the old country so she had the answer. A Muldoon is someone who lives beyond their means. I still don't know the origin of the reference. I may be from a play, or just an adage. I'd still like to hear more, so if you're reading this and you know, please post your information.
Thanks!
