I don't think a family tree would help since many aren't related and I haven't drawn every generation of the families mentioned, but here's as quick a rundown as I can give:

BoneLatch and CarbonTheory are sisters (three other sisters were also shown only recently, WashView, AnglePull and GhostFrame), and FateLock is their great grandmother.

Unrelated to that family, HyssopFall is FlickPin's great uncle, and RainBook is FlickPin's very young son.

Unrelated to both those families, PenWell is the one in charge of the building and legal entity that provides housing for CarbonTheory and FlickPin so is frequently seen with both and their friends and relatives - he's like honorary grandpa. PenWell knows FateLock personally they've know each other a long time. He has a brother, ClayWire who has been drawn only once so far. He had more family but they are deceased, only alluded to at present.

PenWell and ReedWalk were best friends, Reed is now deceased

Character!DimeSpin is not related to Pen they are just the same ethnicity (half the same ethnicity)

Because they live in the same house I do intend to depict Flick and Carbon talking in the future - the culture clash 160-year generation gap between Carbon and Pen is just too funny to me so I keep drawing them talking haha

BoneLatch and DimeSpin are best friends

HyssopFall and AtlasKind are best friends

AtlasKind and HyssopFall trained DimeSpin in spellwriting at one point and they occasionally talk

There are older characters I may or may not draw again but they aren't blood related to anyone above. I drew an Atau once who had a fully fuzzy head and neck I might bring her back because it was funny but if I do I have no idea if she knows any of these people.

One day in the far future

In that image he's definitely too big - he's a proper toddler. I depict his age a little fluidly depending on what part of his childhood and what aspect of Flick's experience of motherhood as a Saratoan I want to depict.

I wanted to draw Rain and Pen together and Pen is too old to do much joey care, but he's happy to hold a baby for a minute, so I drew Rain as "please hold the baby for a second so he doesn't lick a power outlet or something I need to find my purse" age, rather than a delicate newborn

He's "ride on mom's back like an opossum" age in that image rather than pouchling age.

Thanks!
