First Human Giatrus (はじめ人間 ギャートルズ) was an anime series about a prehistoric family set in the stone age, based on a manga by Shunji Sonoyama.
The anime lasted from October 5, 1974, to March 27, 1976, produced by TMS Entertainment and aired on TBS (Tokyo Broadcasting Service) in Japan.
Ocean Studios (a.k.a. Ocean Productions Inc.) produced a pilot for the show under the name The First Family featuring the voices of Matt Hill, Richard Newman, Teryl Rathery, and Terry Klassen. It is unknown if this was aired, and when it was dubbed.
The TMS Entertainment English website has a listing of anime titles with English titles and logos (i.e., Ganso Tensai Bakabon is called Meet the Boneheads, although besides TMS's Malaysian dub edits there's no evidence for an actual English dub.)
The website ended up also listing The First Family with the pilot embedded.
