Okay, I'll tell. My "Mom's" mom and dad were born and raised in Kentucky & Tennessee. My Mom had a female caretaker of mainly African Origin (African-American) and she was referred to as "Mammy" the A is pronounced like Sammy (at least in American English). My mom loved her Mammy I think as much or more than her own Mommy. My mom was born in the 1940s. In our family, on mom's side, This was the last person that was hired, and then she retired or died, that was it. My mom has a lot of stories about her, some of them shed light on America's very racist "apartheid" system (where my mom cried that her Mammy had to have separate seating at a baseball game in St Louis, Missouri etc etc) Sigh ... not to be all political and historical up in here. But that's some context. Other folks may have other opinions and background stories. Experiences and ideas and opinions may vary.
I expect that there would be a lot of Americans (of old Irish background, old as in a century or maybe a few centuries ago ... when their/our Irish Ancestors arrived to North America) I also expect that there are some New Zealanders, Canadians, South Africans, Australians... South Americans etc etc. are also represented here. All trying to learn Irish (and many succeeding?) I can only speak for myself. "is méiriceannach mé agus tá mé ag foghlaim Gaeilge" I'm probably wrong in how I said that :-) anyway, MOM is usually an American thing, that was the main point I was getting at. I'm long winded. I'm from the "Fallon" tribe, I blame it on that.
