The name is part of your heritage and you… Literally. Use it if you want.
Like the names in your signature, btw.
[name]Lakshmi[/name] is a lovely name 
Use it! I personally don’t believe names are restricted to people from their country/culture of origin. I’d get bored pretty fast if I was only allowed to use English, Irish and Welsh names.
It’s a part of your and your child’s heritage. [name]Just[/name] becuase your outer appearance doesn’t make your heritage obvious it doesn’t mean you have to ignore it. You’re showing pride in your family and heritage and that’s wonderful regardless because you’ll pass that on.
Use it! [name]Lakshmi[/name] is part of you, and your heritage just because your child may not have the outer appearance of an [name]Indian[/name] does not mean that she doesn’t have that heritage and that the name [name]Lakshmi[/name] isn’t part of her. Personally I think the name is gorgeous, she’s really intriguing and would be a great choice.
I think you should use it. Not many people are actually going to know your baby’s middle name so I don’t see it as a problem.
I see no dilemma! As others have said, it’s part of your heritage and therefore your child’s. You should use it!
Ditto to all the comments above.
Plus, for listeners of NPR, [name]Lakshmi[/name] (Singh) is a familiar name.
