Donna, I think Janet is trying to edit her LNAB on Wikitree, not in a court of law.
I've mentioned this on G2G before, but I was given a LNAB that does not belong to either of my biological parents! And no, I wasn't adopted nor am I, strictly speaking, an NPE. My mother had been divorced from her husband (who gave me his last name) for 10 years around the time I was born, no one seriously thought he was my father. My LNAB resulted from the bizarre personal decisions made by my parents.
