This is a tough one!

Do we have any members in West Virginia or Arkansas that might be able to help us out here?

Explain how this may be.
Let's see... I can get it almost, if the grandmothers marry each other's sons, but I don't see how this can be incest free... when it also says sisters and brothers.

The last line of the puzzle clearly indicates that incest is required.

Oh, I thought it said that incest was not allowed! From incest clear = no incest?

Otherwise:

Identical twin sisters married one man (or identical twins), who gave each of them a son (making the sons genetic brothers). Then he died (so he's long gone). The two widows then married the other's son. And then each had a daughter.

Are we allowed to count "in-laws" and "steps"?

If so, I can do it:
A man (A) marries a widow (B) who has a grown up daughter (C).
The daughter marries the man's father (D), and they have a daughter (E).
And then A and B have a son (F). That way, the relationships are recursive. Here's a graphical depiction:

A - B
...| .\
...F. . C - D
............|..\
............E ..A - B
....................| .\
....................F.. C - D
...........................|.. \
...........................E... A - B

Two grandmothers, with their two granddaughters,
B is the grandmother of E, and C is the grandmother in law of herself (her mother's mother-in-law).

Two husbands, with their two wives,
A and B, C and D.

Two fathers, with their two daughters,
D is the father of E, A is the step-father of C

Two mothers, with their two sons,
B is the mother of F, C is the step-mother of A

Two maidens, with their two mothers,
Not sure what "maidens" means here, but B is the mother of C, and C is the mother-in-law of B.

Two sisters, with their two brothers,

E and A are (half) brother/sister, as are F and C

Yet only six in all lie buried here,

check

All born legitimate, from incest clear.
Biologically, they are all incest free.


There's an old song ("I'm my own grandpa") which is about a family which is almost, though not quite, like this.

I'd be guessing that "maidens" would be unmarried virgins.

Yes, that "from incest clear" statement in the context can be read either way it seems. If you can do it without the incest, that seems more impressive.

Ok, here's the answer that was given: Two widows each had a son, and each widow married the son of the other and then each had a daughter.

I'm not sure if anyone came up with this exactly, but as far as I can tell, it works. This riddle got more confusing the more I looked at it and the more I read the answers that were posted.

So who are the sisters and brothers? Or are they sisters and brother's in law, only?

Each widow has one son and one daughter, so there are two sets of (half) brothers and sisters.

Okay, looks like Dilettante gets the credit here (and moves into the lead on the scoreboard!).

You're up.
