Hi Stephanie. Could you possibly provide a little more explanation about what you're trying to do? Normally we only merge things when there are two profiles on the site for the same person, and I'm guessing that's probably not the issue here. When you say your 12th cousin is on WikiTree, I assume that means he has a profile on the site (and is perhaps a living person who is also a member?) If you're just trying to show your connection to the person, then I agree with Eddie -- you would do that by building both of your ancestral lines back as far as the common ancestor. That might be a fair bit of work that will take some time for a cousin that distant, but if you know it's a 12the cousin, then presumably you have enough info to do it..
