The relationship finder gives you your closest relationship with a given "person"; it won't by itself, give you 2nd, 3rd, etc. If you are related to the person through your father's side, check out your mom's relationship with that person. You could be 3rd cousins on your father's side and 4th cousins on your mom's. This way you can work your way backwards to a given person. The relationship finder will give up to 15 generations on the first go and 30 on the 2nd one.
