Will the real "Spears" please stand up!

Well, well, here we go again, genuine Hollywood power struggle... It seams Britney "Spears" is claiming her decent from; and thus ownership of Sir William Shake"Spears" works... While on the other side there is on Burning "Spear" claiming that his great, great, great, great, great grandmother had relations with Sir Williams as his maid... Thus securing his lineage and thus ownership of Sir Williams works... DNA to the rescue?!?
