Under "Geschlecht" There are two columns "M" & "W".
In one column or the other a large "K" is written but it does not appear to be in the correct gender. for example one is under "M" when the given name is Sophia. Which I understand to be a female name.

Does the "K" indicate gender.

The problem I have is, for many of the given names listed I don't know which gender they are.
