What do you do when a parent's gender is ambiguous?
I'm indexing South African records with a "Parent name" column, but separate fields for Father and Mother. When there are two names, I'm using context to decide which to list as father or mother. But when there is only one name given... do I fill out both mother and father with the same name, or assume it's the father, or assume it's the mother? Finally, does it make a difference if no first names are given? Or if the person is older, as in this example?
