> Noelia Noel

She is from Argentina. Both are common given names and family names here. Neither is in the top 10 list, but they are not unusual to cause surprise. I'd recommend to avoid using both together to avoid nasty online comments.

> Astha Astha

She is from India. Astha is a common given name there. It looks like it's common in some areas to have only a given name and no family name. I guess in some form she was had to fill a family name and decided to repeat the given name instead of using NULL.
