Is it a risk to have children with your 5th cousin?

There is always a risk when having children. The mothers have a risk to their health, both parents risk stress and financial issues, and there is a risk that any child may have a birth defect. The risk of birth defect in the child of two fifth cousins is essentially the same as the risk for a child of "unrelated people." Consider that most of us do not know who our fourth or fifth cousins are and so may marry one without realizing it.
