On The Couch
SHRINK RAP: I feel uncomfortable because my cousin is marrying her uncle. Will they have strange children?
The concept sounds strange and even repulsive to modern Western ears, where these practices are rare and frowned upon.
Logically it makes sense to marry family members because there is shared history, culture and values within a family that makes family members often more naturally compatible than people from very different backgrounds. Family members naturally care more for each other and are more loyal than they are to strangers.
In some cases the female member of the partnership would like the opportunity to carry on the family name if there are no males to perform that function.
You need to work out what thoughts and beliefs are driving your feelings. You might find that your reaction is not just fear about genetic consequences of this union, but has to do with your own values, beliefs or even prejudices. - Leonard Carr
I am curious about which aspect you find so uncomfortable? Is it the age difference? The familial connection? The fear of children with disabilities?
In these situations, information is helpful. A brief glance on Google medical pages suggests the risk of such a couple having ''strange children" is minimally more than a non-related couple.
If the uncle is considerably older than your cousin, this may be the most disconcerting factor for you.
Try to be positive about your cousin's choice and ask her to share her motivations. Instead of judging them, wish them well. - Stephanie Dawson-Cosser
