The “last names” Nmi, Nmn, Lnu

Some genealogists when they have an unknown name want to put something in that blank. That’s why in some databases you will see things such as:

  • Nmi–No Middle Initial
  • Nmn–No Middle Name
  • Lnu–Last Name Unknown
  • Unk–Unknown
  • Blank–Blank [be careful as Blank can be an actual surname]

My personal preference is to not use such terms. If you feel the need to put something in the spot, use actual blanks or dashes.
