My Paternal Grandpa's sister, married my Paternal Grandma's brother, how do I get the family tree to do this complex relationship without having to create entirely new repeat ancestors.
Please tell me the way in a detailed description of how to correct this please.
Unfortunately at this time there is no way to add complex relationships like two brothers marrying two sisters online. The only option available is to add their information twice. We do hope to have this feature in the very near future. If you wanted to work in the free downloadable Family Tree Builder Software, there is a solution for situations like these. Please see the following post in our FAQ: http://www.myheritage.com/help/2008/11/how-do-i-show-one-person-in-two-locations-in-family-tree-builder/en/
