Hi Detori
I'm not sure if those are totally complete runs or not. There are a few spaces on the IGI for Cumberland.
Whether it is pr not though, at least one of the two largeparishes are indexed. Caaaan't remember if they both are.
The main problem we have here, is people saying born Carlisle, when they really mean the area and there are loads of tiny parishes close to Carlisle, so it can be a case of just plodding through them.
They do have other records up there for that era though such as wills, taxes etc, and also some indexes to some of the local parishes including Brampton deanery. Certainly there are gaps for some of these parishes on the IGI.
Best wishes
