I may be hitting on an already settled issue, but I cannot recall, with all the discussion on lnab's, whether the issue of those from the Netherlands came up. Though not all are aristocracy, this group has discussed this the most. I am cleaning up some profiles from my Van Sickle line, which marries into the Bantas. Far enough back the last names technically switch from a single surname to using the father's name for the surname. Should I keep the father's name (birth name) as the lnab and use the common surname as the current last name, or vice versa? Or neither?
