Maybe I am missing something, but it appears that the only way you can have a child listed as being the offspring of both mother and father at the same time is to put both parents down and then children. I cannot add the connection to a parent unless I then disconnect from the other parent(father/mother). Essentially what I'm asking for is the assumption that the child of one parent is the child of that parent's partner or at least the ability to, and then have the ability to disconnect from that partner if you want to, without disconnecting with the real parent. There does not seem to be any way to do this if the relations are already there and disconnection/connection are made. For instance, I had children incorrectly attached to a set of parents who should have correctly been connected to the man's brother. So I then disconnected from the one and reconnected with the other but could not connect the children to both new father and new mother at the same time even though the new parents were already shown as partners.
Henry DeTrafford and James DeTrafford are brothers. I would like to remove a connection of one of them from one set of the parents, and reconnect to the other set(doesn't matter which one right now) and have both of them recognized as siblings with the same set of parents, both mother and father.
Noam pretends he has not seen this problem before. It is common! I have made many references to it, and am extremely careful when adding people now because of it, especially when it comes to linking "known" or existing people. You must link parents first, then in the classic view add the children. If the child already exists, and can't link to both parents, you are kind of stuck. If there is not alot of lineage below them, the easiest thing is to delete the child and then add them to parents in Classic view.
