its not who marred who, they use your DNA to see whose blood you have in you and thats how they tell if you related. if your sister marrys someone, and then you marrys ur sisters husband brother, your not marrying you cousin bc they dont share you blood. does that make any sense? im not sure if i explained it the best.
