Foreign language names are not translated in Hindi but are used as such, however as Hindi is written in Devnagari script the appearance will be different. I mean when kathryn is written in hindi it will look differently.
If you are looking for kathryn in devanagari script pls. mail me your e-mail id. I will send you kathryn written in Hindi.

You

Names in Hindi are translated as it is.
If you want to see the name in the Devanagari script (which is the script used for Hindi language), then you will have to provide your email address, since it is not possible to load image-files on this site.

When you send the image file, then the translator can send you the image file containing the name written in Hindi (Devanagari script).
