Solution There are actually two valid solutions !!!! | Comment 25 of 53 |

If a valid solution must specify even the sibling relationships (it doesn't ask for that, however), there are two distinct solutions, since one's brother-in-law can be either the husband of one's sister or the brother of one's wife.

In the first solution, the piano player is sitting next to the husband of his sister, and in the second solution he is sitting next to the brother of his wife.

Solution 1:

Hostess and horsewoman Betty, wife of host George, is sitting at the west end of the table.
To Betty's left, at the north end of the table, is piano playing Frank, husband of Donna.
To Frank's left on the north side of the table is fisherman Edward, husband of Alice and brother of Donna. (Edward is Frank's brother-in-law since he is married to Frank's sister Alice).
To Edward's left is actress Alice, wife of Edward and sister of Frank.
To Alice's left, on the east end of the table, is rose-loving host George, husband of hostess Alice.
To George's left, on the south side of the table, is needlepoint expert Carol, wife of Harold.
To Carol's left is stamp-collecting Donna, wife of Frank and sister of Edward.
To Donna's left on the south side of the table is model plane builder Harold, husband of Carol.
 
Solution 2 is like solution 1 except that now Carol, not Alice, is the sister of Frank. (Now Edward is Frank's brother-in-law because he is the brother of Frank's wife.)
