I have created a huge tree without any LastName. Now I have learned the correct LastName and need to apply a mass change and provide everyone in tree the same LastName information. How can I do that ?
Although there is no formal way to change many profiles at once, what you can do is the following:
You can go into your tree in Family Tree Builder and into Edit > Export To Excel and choose to export a list of people. You can then edit the list, and then re-import it.
