I'm currently breaking down my Albea family brick wall. It's a bit confusing right now, with the discovery that my ancestor, Thomas Albea, had two wives. So, I need to move some of the children around between spouses. Using Reunion, I can do that rather easily - but it took me a while to figure this out so I thought I'd share it.
Here's what my initial family looked like:
Now, my software will ask me to verify how exactly I'd like to add Sarah to George's record. In this case, I want to move George to the record for Thomas and Sarah. This way, I don't end up with mulitple listings for George or random, unattached individuals floating in my software. If I was unsure which woman was George's mother, I could duplicate George and have him appear as a child for both of Thomas' wives.
Now, you can see that George's parents are listed as Thomas and Sarah:
This method can be used for a number of other events in Reunion, such as adding a second marriage between duplicate spouses or creating links between two ancestors already listed in your tree.
