I know that similar questions have been asked before, but not quite the same.
An example: I find a burial record stating only something like “on (date) The mother of Peder Pedersen was buried, aged 84 years” I do not know the name of Peder’s mother, so should I create an “unknown” profile and add the approximate birth year and death date based on this information or should I just write it as a note on Peder’s profile.
