Western Animation / The Roman Holidays

The modern Iron Age family.
This animated series from Hanna-Barbera is about a Dom Com family in "ancient" Rome. As on The Flintstones, Anachronism Stew is an essential part of this series—but the starting point is later.

The head of the family is Augustus "Gus" Holiday. He has a wife, Laurie; a daughter, Precocia, and a son, Happius, or "Happy"/"Hap" for short—much like The Jetsons (although unlike that show, this family features an older brother and younger sister). Their pet lion, Brutus, is a Big Eater.
