One crazy thing I found out is that about half of folks born & raised in my native Oklahoma are of Irish descent, and my ancestors on both sides of my family have been in the States for well over 200 years.
The oldtimey way of speaking that my Irish grandparents & many folks in Oklahoma have is somewhat like some of the folks more I've known who came over from Ireland in more recent years. Most Okies of my generation have heard their parents use words which are Irish-we just didn't know it. For example, most everyone I grew up with heard their parents tell about the shivaree their friends & family gave them. But then, I've also heard older folks from Tennessee, Virginia & other states talk about a shivaree, too.
   Most all Okies I came up with say "Ah'm fixin' ta git me sumthin' tuh eat!" Some even say ". . .finntuh . . ."   But it does make me nuts to hear some feller say, "Ah'mo tak'n git me sum'mmtuheet."
