Question

JavaScript

Hello) it's already the third week, and I'm still fighting with the family tree, which can have several children, and each of them has several parents. Advice yes, the structure is not like a tree, but a little more complex.
At the moment, it seems to me, almost everything is ready BUT! ... There is one thing but .. If you look at what happened
Here jsfiddle.net/egfx43hs/13 then where children come from me and my wife - not very beautiful (I wanted it would be better to display it somehow ... Like here
Do not judge strictly, I don’t know JS. I didn’t expect that I would encounter such a problem that I don’t even google, PHP and mysql have already been done, and add, and change, and links install, and delete ...
But this turned out to be a big problem.
I hope there is no one else to turn to for your help.
