At the moment one responsive manager has put it in the unmerged match tray, let's just say they agree and say 'match', what will happen next?
The merge will not be allowed to take place until the other manager either makes a response of 'match' or thirty days,
After thirty days either it will just stay there as a match but no-one will merge due to the information of basic information being different, OR they will merge incorrectly and therefore alter the dead of death etc, OR it will be placed in the unmerged match tray with a comment place of birth and time of death differ more research needed.
Have a look at the the Pending merges - There's some in there from some time ago possibly due to the above reasons
