Is it OK to date your 2nd cousin?
In the United States, second cousins are legally allowed to marry in every state. However, marriage between first cousins is legal in only about half of the American states. All in all, marrying your cousin or half-sibling will largely depend on the laws where you live and personal and/or cultural beliefs.
What relationship is a second cousin to you?
It means that the closest ancestor that two people have in common is a grandparent. (If they were any more closely related, they would be siblings.) Second cousins means that the closest common ancestor is a great-grandparent. Third cousins, then, have a great-great-grandparent as their most recent common ancestor.

Why we should not marry cousins?
Children of first-cousin marriages have an increased risk of autosomal recessive genetic disorders, and this risk is higher in populations that are already highly ethnically similar. Children of more distantly related cousins have less risk of these disorders, though still higher than the average population.
Yes, it is possible to share a small amount of DNA with someone and not be related. In other words, its possible to share genetic material and not share a common ancestor. DNA segments that are identical-by-descent (IBD) were inherited by each DNA match from their shared ancestor, or shared ancestors.
Does the Bible allow cousins to marry?
Must first cousins be forbidden to marry? In the Bible, and in many parts of the world, the answer is no. But the answer is yes in much of church law and in half the United States. This Levitical law is found in Leviticus 18:6-18, supplemented by Leviticus 20:17-21 and Deuteronomy 27:20-23.
