Well, kind of, it was just over two years ago they passed on to me. One was even her mother's cast iron before her. My grandmother added to the collection then passed them to my mother, who in turn passed them on to me.
I used steel wool and soap. Scrubbed them until rust free and then seasoned like in the video. Now I use a sponge and salt with hot water and salt to clean. Never use soap or detergents because it weakens the seasoning. I heat dry (just like my grandma) and then oil and heat again before storage.
The video could have been made by my grandmother. It's that excellent!
Thank you for sharing. 
P.S. If yours have any crud on the bottoms you need help removing, spray with oven cleaner and place in a trash bag overnight. The next day it should clean off with just a touch of scrubbing. Then season as if it were new.
