Now you've got them both as the wife instead ;-)
I suggest you leave Christian-2048 to be Alice Gertrude - she WAS born a Christian, so the last name at birth is correct. She does need to be connected to their common daughter (Christian-2042)
Christian-2047 needs to be changed to Clifford Thomas - no need to retain the Anonymous. He also needs a gender change (there IS a toggle for that). His last name at birth is also, correctly Christian, which is lucky - no need for an awkward change there. I guess he also has other dates of birth and death. It's all a bit fiddly, but no disaster.
