[name]Lacey[/name] (Too nicknamey?) - I think it sounds too “lacy,” like lingerie.
[name]Lauren[/name] (Too common?) - seems to have been popular; I think it is a good name (it’s my sister’s name). I don’t feel like it’s too trendy. [name]Laurel[/name] or [name]Lorelei[/name], or even go out on a limb and try [name]Lorraine[/name]; we knew a Laurain, and my sister was so jealous! [name]Lorena[/name] is a no (for me). I still think of the Bobbitts, but it is a pretty name.
[name]Leslie[/name] (Too masculine?) - I have never really liked this name, but these days, I don’t mind it too much. I think it’s hard to say, has some teasing potential, reminds me of bugs for some reason. Not too masculine.
[name]London[/name] (Too trendy?) - Yes, too trendy.
[name]Louisa[/name] (Too old?) - it’s old, but not in the “too” sense, it’s in the “new again” sense; people are looking at this name again in the fashion to revive old names. [name]Luisa[/name] is also cute. I would say [name]Aloisa[/name] (I love it slightly more than [name]Eloise[/name]), but you are asking about L- names.
Other options I like:
[name]Lena[/name] - I see you are attracted to this. I have gotten extremely fond of this lately.
[name]Lucia[/name], or [name]Lucille[/name] - I think [name]Lucia[/name] is classic and beautiful, while [name]Lucille[/name] is just peeking out as a renewed possibility, as [name]Lucia[/name] seems so safe and obvious (but definitely classy).
[name]Lisbeth[/name] - a twist on [name]Elizabeth[/name] that’s very interesting.
[name]Lenore[/name] - or [name]Leonore[/name] - I think nameberry doesn’t have very positive things to say about [name]Lenore[/name], but it is close to [name]Eleanor[/name], and one of those old names like [name]Louise[/name] or [name]Louisa[/name] I think people will start to think about using soon.
[name]Lavinia[/name] - I don’t love this name, but it’s hard for me to dismiss it. It’s another one of those “old” names people are looking into dusting off.
[name]Livia[/name] - similar to [name]Olivia[/name] but with a different origin. People may think it’s therefore made up because they haven’t seen it around. It may not seem distinctive enough for you.
[name]Lila[/name], [name]Layla[/name], one of those kind of names. [name]Lily[/name] also. [name]Lily[/name] feels sort of overused by now, but I love [name]Lila[/name] and [name]Layla[/name] (or spelled [name]Leila[/name]). By contrast, I think [name]Lola[/name] sounds like it’s supposed to be short for something like [name]Laura[/name] or [name]Delores[/name], so I don’t recommend it in this group of L-l names.
[name]Laurentia[/name] - another one close to [name]Lauren[/name]. While I think [name]Lauren[/name] and also [name]Laura[/name] are just tight, easy-going, non-controversial forms of the root, [name]Laurentia[/name] is a little on the exotic side, and ancient besides.
[name]Lara[/name] - even tighter than [name]Laura[/name], very good short name like [name]Lena[/name]. Can be called Lah-ra or Lair-ah, and people will pronounce it both ways; if you prefer one way, and you like people to get it right the first time, this name may not be for you.
[name]Linden[/name] - someone suggested this earlier, I think it is pretty. It’s a name of a tree, and everywhere I’ve ever lived, also a street name (after the tree). I kind of like that, you can take a picture of the sign and hang it in the nursery, or pictures of the tree. [name]Lindy[/name] is a cute nickname, and also a dance step, after the [name]Charles[/name] [name]Lindbergh[/name], Lindy Hop - Wikipedia. Interestingly, the [name]Charleston[/name] was also named for him.
I’m not scouring the lists, so I’ve run out of ideas off the top of my head. I hope you consider some of the ideas.
