I am happy to see you are still working on your Blanton profiles! I added Eli Bibby's wife to the Blanton Name Study and expedited the merge under that project since I know you have been trying to get this resolved for some time and the manager of the other profile has not actually been on since December 2015.
For future reference though, the correct last name at birth goes in the bottom slot when merging. What I do is put that in the merge request (Bibby is the correct last name at birth) along with good info about how you know they are the same person and make sure you mention a source for the LNAB (last name at birth).
Then, I copy that message and put it on the other profile so it is on both. Right now the message only shows on one automatically.
Next thing to do sounds like overkill but still, it's a good idea.
Post a polite message on the profile page of the profile manager asking them to approve the merge and contact you if they have any problems or queshons about it. Then I send them the same message in a private message from the profile you want them to merge.
Keep track of the time. If you have had no response in 10 days, send and post the messages again. If still no response, see if a leader can help you. You can also file an unresponsive manager request but I think we have one guy handling those so I try to help resolve those if I can.
Back to the merge - you can also put info such as correct dates and/or places. Those can he easily changed so if there are different last names I keep it simple and stick to that. If not, adding which date is correct (have source!) will prevent someone from setting the merge as an unmerged match!
One last hint! I try to make friends with people I find sharing the same profiles because it is an easy way to begin collaborating!! I know you already do that because we both have Blanton profiles!!
