Curiosity got me to do a bit more research. Scheirbrock was his father-in-law.
I never bought GM’s but they were huge in the area. I had a co-worker who went to school with his daughter. He said she was “a stone fox.”
I’m guessing his daughter went to Catholic schools, with high school being Assumption, which was only a few blocks sw of the dealership.
I’m thinking that because Lujack was famous, and a handsome fellow, Scheirbrock’s daughter was surely a doll. So it doesn’t surprise me that a Lujack daughter was pretty. I read that of his three kids, the oldest and youngest were girls. I was sad to see the youngest only lived to 48. She was born in 54 like me.
