What's wrong with that name. We have given Sikh names to our children and in some schools they went they were the only Sikhs in the whole school. If any child dared to bully them we were in the Principal's office making sure that the issue was dealt with immediately.
Their Sikh identity and names did not stop them to excel at school and also become Student leaders.
Like I said it totally depends upon the parents to lead by example and show them what Sikhi means in daily life.
