Feature Request: Support for Parenting with Couple Elements

[rayaanr]

This repo is about organization charts, but I'd like a feature that represents pairs, such as parents in a family tree (picture below).

I'm creating a family tree & unable to find a library that allows the adding of React elements directly to the tree. This is the only library I've found that comes close to meeting my needs. Therefore, adding this feature would be incredibly useful.
