Hi
I came to this one a bit late, but I'm a bit confused too!
If the list that Lorimer found was in the actual records, than the baotisms must be there. The only thing I can think of is that these old records tend to jump around as new books and rules were introduced so that all of the reel will not be in chronological order.
On the early part, there will be baptisms, burials and births, possibly a group of each per year, or even mixed up so needing a lot of reading, then among other changes a new marriage book comes in, so marriages are separate and eventually there are books with forms for all three events so they are separate.
This often means the reels jump around a bit and especially around 1800 you may get a small piece of register well away from the rest or even on another reel.
OIf these were still the submitted ones, then the area may be right but the church is passed down by word of notes or family notes and we can look else where. This area's still quite sparsely populated and most people won't live by the church.
My next choice would be Sebergham. Some chapels weren't open at this date or didn't do marriages. -Failing that, some older parishes would be Caldbeck, Dalston, Skelton or Greystoke, and of course some people even went to the towns - Penrith or Carlisle.
I would try Sebergham next though.
Best wishes
