I had a number of spouses in my ancestry tree that had the wrong (i.e. husband's) last name. I realized when I created my new RM database from Ancestry and merged in the GEDCOM from MyHeritage I would have duplicates, so I used the name clean feature to clean up a large number of spouses and merge them with the MyHeritage spouses that I'd removed the last name on already.
Now I have a whole bunch of wives in my database with no last name and want to sync that information to Ancestry to assist in finding the real maiden name. RM sees the change, but does not give me the option to blank out the name in ancestry.
How do I remove a last name via TreeShare?
