Pronounce R's after N's ?

In words such as Henry then it's pronounced 'hen ree'. In England there is a town named Penrith, pronounced 'Pen rith'. In other words the name is split into two sections, or syllables, ending one with n and starting the other with r.

I think I can't pronounce R after N like these words Henry ,my own reality. Can anybody tell me how to pronounce r after n ?

Ruh. Think Henry.
