Liz's daughter directs the episode "An eagle feather, a string bean and an eskimo" last Thursday on CBS. You can see it online at CBS.com. Her credit is at the 4:40 mark. I was surprised to see her name as it came up, it's the first of this series she's directed.

If you check out her IMDB page, she's done a lot of the bigger modern shows... Brooklyn Nine Nine, Superstore, The Good Place, Black-ish, This Is Us...

She's also done a few episodes of American Housewife, who have also used Jean Stapleton's son John Putch quite a bit.
