You know, there is nothing wrong with sticking out in a world of Megans and Kates
And really, your child WILL stick out anyways -- the reality is they will be a different "color" than all those Megan and Kates and have a significantly different past history than those same kids.
Yes, there are parts of that that will be hard for them, but there are also parts of that which will mold them in wonderful ways.
I can understand your reasons for wanting to change, but remember, the underlying issues never will - name change or not. Your child will be of Indian Heritage, be Indian in looks and appearance and will be perceived as Indian when she interacts with the world outside of your protection.
