@DaveSch Wouldn’t it be a bit confusing to call this filter “Male Line Descendants” if it only includes male male-line descendants? From the name only I would have assumed it includes female male-line descendants too (vide Filter for male-line descendants) Is there a reason why someone might want all patrilineal descendants (including adopted sons) but not daughters? Perhaps it would be more intuitive to have a filter that is called “Patrilineal descendants” that would include all male-line descendants (male or female) - and then the user could easily add the gender filter on top of it?
