I have a question. What do you think about a family who had practiced marrying only their first cousins ,( mothers nephews/ nieces , fathers nephews / nieces ) for hundreds of years marrying only the first cousin? I want to know the Health repercussions . Currently my sister and a few more are labeled as infertile.
