How to create a cycle in a genealogy tree?

Question

I started a Family tree using the genealogytree package. The tree starts from the bottom (from me) and goes up. However, my (maternal) grand-grand-father and my (maternal) grand-grand-mother share the same (paternal) grand-grand-father, who is my 5th grand-father, which means there is a cycle.

When I try to draw the Family tree it looks like this:

The person in the top is the same, but appears twice. is there any way how I can merge both entries into one entry so the person appears only once?

This is the code I used to generate the family tree:

Answer 1

I have removed one abdellah parent, shifted the other, and drawn manually an extra edge between the unique abdellah and the Mhen child (maybe there's a better method but I don't know it).
