It doesn't seem to travel well. I've never come across one in South
Africa. Very many
Lynn and
Linda people, and Lindsay/Lindsey as well. And a couple of Lyndall ones. In my order of preference they'd be Lyndall;
Lindsey;
Lindsay;
Linda; and finally
Lynn. And
Linnea seems like a fussied-up
Lynn, although I know its floral origin, so I wouldn't use it at all.
