My cousin immigrated to America.

Ridiculous. You are blood relatives, no more than three generations. If you have children after marriage, you will get genetic diseases. Stop talking about you. Even your son can't touch her daughter. It will take four generations to combine. It is forbidden by law, and junior high school biology also says it. How did you go to college? Ridiculous, incest, stop! It is destiny takes a hand that you can't be husband and wife.
