Please, people who will read this, know that most of the time, although, I have never came across an actual surname, Lnu, that Lnu means LNU-Last Name Unknown. I get so frustrated when I see a number of the females in my ancestral past have been given the last name Lnu by distant cousins.
Ok...just needed to point that out. I just saw yet another tree with my 5Great Grandmother, Mary, with Lnu as a surname...
Below are links to ref about last names and LNU
