Identical individuals cannot be merged
Sgt. Thomas Hill Michael, 3 June 1917 – 19 September 1944, • MHR1-3N2 and
Thomas Hill Michael, 3 June 1917 – 19 September 1944 • G88R-BJQ
Cannot be merged - reason is A parent cannot be merged with his or her child, although there does not seem to be or to have been an instance where these two could be construed to be parent and child.
I have checked all the changes to both, removed MHR1-3N2 from all relationships to see if they can be merged.
I added G88R-BJQ to the parent, so they show as brothers.
Merge is still not possible.
There's another thread about a similarly-inexplicable occurrence of that error message: https://community.familysearch.org/en/discussion/comment/498802
I have not been able to figure out what's going on. At this point I'm fairly certain this is some sort of bug.1
