Carol adds:
Maybe the missing piece here is Bellatrix. In HBP ("Spinner's End"),
she says "In the past he has entrusted me with his most important--"
and then breaks off (quoted from memory). In OoP we discover that
Kreacher treasures her photograph. Suppose, for the sake of argument,
that LV entrusted Bellatrix to place the Horcrux in the cave, that for
reasons unknown she brought the devoted Kreacher along with her, and
that Regulus somehow found out about it and ordered Kreacher to go
back to the cave with him? I'm guessing that Bellatrix was a frequent
guest at her aunt and uncle's house or at least a favorite relative as
they kept a photograph of her and their house-elf was devoted to her,
so Reggie might have overheard a conversation between Bellatrix and
Mrs. Black.

I'm not postulating that either of them was the potion maker (a
permanent sticking Charm is not a potion or evidence for skill at
potion making), and I have no idea how Reggie figured out that the
locket was a Horcrux (I doubt that LV confided that information to
Bellatrix or she to anyone else), but I do think that the
Bellatrix/Kreacher link will prove important. And of course Kreacher's
addled brain could be explained by having been forced to drink the
potion (I don't think Regulus would drink it himself, and we see
Slughorn using house-elves to check for poison, so we have a precedent
for that use for a house-elf's devotion).

I'm very much aware that this is not a full-fledged theory, but I'm
wondering if anyone can provide additional support for it.

Carol responds:
Mrs. Black's references to "the house of my fathers" are puzzling as
it ought to be "the house of my husband's fathers." (Maybe she had
lost all sense of her own ancestry in adopting her husband's family
identity as her own?) IOW, she's a Black by marriage, not by
birth--unless Mr. Black married his first or second cousin, whose name
was also Black, in which case the brothers Sirius and Regulus are
lucky that they weren't as abnormal as Merope and Morfin Gaunt,
especially since their mother seems to have been somewhat elderly when
she gave birth to them. 

But to return to the point, unless she was a Black by birth or her
mother was a Black, she wouldn't have been named after a
constellation. (And if her mother was a Black, the "house of my
fathers" reference must skip a generation.)

Carol, thinking that Narcissa (a Black by birth) should have been
Cassiopeia
