To my surprise, my x's dad had a bug up his butt about having, apparently, either been illegitemate or suspected of same, and when his (the dad's) daughter had a kid by herself after getting tired of waiting to find a (worthy, to her) man, for the longest time Pappy wouldn't acknowledge the fact of his grandson, and when we were expecting our own kids (Mario was 8 by then) he would say If there's a boy I'll finally have a grandson and stuff like that. So I'd say it was alive and kicking in rural US as of the prior generation... although we couldn't care less in ours...
