I did a little digging, and here's what I think. If you just type in, "The Freemakers" Into Wookieepedia, it comes up with an article about the family that is canon, so I think that some of the characters are canon, but we only know that they existed, and the events of the show are non-canon.

I mean, technically, wouldn't RO-GR be considered canon if the LSW: All-Stars series is considered canon? Bc that's where his autobiography episode is

All Stars is non-canon

Ah I see
