Lyndon is my granfather and my aunt's middle name.
My grandfather doesn't like the association with LBJ either, but I actually rather like the name
Lyndon. I wouldn't worry about the LBJ association if I were you, if you like it that much then use it : )
I prefer the look of
Lyndon over
Linden. I think that
Linden works better on a boy than a girl.
