Well I tried a few things without Success. One problem (I think) was that the birth date was listed as before 1911 and I think the system somehow thought that meant it could be before 1500 and wouldn't let the (Unknown) last name be changed. Another problem is that you need to put an underscore between the Von and Punzelman. but though I tried changing these two things it still wouldn't let me edit the LNAB thinking it needed someone with the before 1500 badge. Hopefully someone with that badge will come along and make it work.
