I have the same problem: I need to link existed pearents with existed child. And there is no way to do it through web interface. I know how to link them in FTB, but in that case there is a LOT of troubles with importing and exporting and then re-linking already registered (on the site) people witth imported from FTB family database.
There should be some way to link existed members, not just add new ones.
Hi, Thank you for writing to us. Unfortunately at this time there is no way to add complex relationships like two brothers marrying two sisters in an online tree. The only option available is to add their information twice. We do hope to have this feature in the very near future. It is one of the thing being worked on as we speak! If you wanted to work in the free downloadable Family Tree Builder Software, I could let you know how to manage such a situation. Best Regards, Esther /MyHeritage Team
