YES
There is no doubt that a Pokemon with its Hidden Ability will evolve with the evolution's Hidden Ability or not.
The answer is just clear. YES
In Pokemon White two I got myself a Teddirusa with Honey Gather (By trading with Yancy) which is its Hidden Ability and it evolved to a Ursaring which had Unnerve which is the Hidden Ability.
This is the same for Darumaka and any Pokemon with Hidden Ability evolve with the Hidden Ability of the evolved Pokemon.
