It is fine to throw your own exceptions if they add information, but don't swallow the exceptions from the underlying services unless there is a security concern.

If you are catching one exception and and throwing a new one, assign the old one to the InnerException property of the new one. You can nest as many Exceptions as necessary in this way, which creates a hierarchical "view" into how the exception propagated, which is very helpful for debugging.
