I always called them "pantyhose" or "hose" for short. I do remember hearing my Grandmothers (who were born in 1911 and 1918) refer to them as nylons. I am in my late 30's and live in Indiana.

Growing up in extreme southwest Indiana, we always said "Coke", no matter if it was Coca Cola or Pepsi. After I was married, I moved to Northeastern Indiana, and up here it is "Pop." Hubby has tried hard to get me to say "Pop"...he was born and raised here in NE Indiana...
