I think geneticists would say that first cousin marriages between healthy individuals over two generations would increase chances of health problems, if only slightly. The problem occurs if individuals carry genetic abnormalities or when the close marriages are repeated again and again. The repeated marriages in the Hapsburg family in the 16th had 17th century, between double first cousins and Uncles and nieces, was a medical disaster.
