If it is in the notes area, it is likely someone's personal secret code or abbreviations that only they understand. A lot of this type of thing has been imported from notes that were created in, and specific to PAF or Ancestral Quest (and possibly other PC tools). In those applications there were ways to search your database notes for things that you might call "flags" or "tags". Unfortunately when they are imported into the FSFT (usually by the use of GEDCOM files), we get all that extra garbage that is not useful to anyone else other than the originator.
I wish that folks would not do that. I have some ancestors with 50-70 notes attached all containing that kind of gobbledy-gook. Makes it extremely hard to find notes that are really useful and informative.
probably only means anything to the person who entered it. and probably means nothing to the rest of us.
(some sort of notes)
try contacting the submitter if you can.
Yes. The contact name for the person who last changed the note (usually the originator) can be seen at the bottom of the note when it is opened.
