I don't know where to put this, but 23andMe thinks I'm the result of inbreeding.

All Funny!
For context, the weird part is "Grandmother, Both Sides". Given that mother and father are qualified as "Mother's Side" and "Father's Side", respectively, "Both Sides" seems to imply that this same one person appears on both sides of the tree, I.E. Mother and Father share a mother.
No idea if this is actually what 23andMe is trying to say, or if it's just really poorly worded.
