Kirkby Ireleth, Satterthwaite, Urswick, (Hawkshead possibly) are all within a reasonable are for Holker but I could only find 5 baptisms between 1879 and 1889. I discounted the Bolton le Sands ones as being the wrong side of Morecambe Bay and Warton as a bit too far
I used a 15 mile radius on Cartmel which gave the return that I quoted.
Bolton le Sands and nearby Warton are easily possible, do remember that the route in those times was from Bolton le Sands across the sands of Morecambe Bay to the Grange Over Sands area. It was a walking route and a coach route. The Queens Guide to the Sands was and indeed is presently tasked to route a safe passage across the sands to travellers.
This route is still in use today by thousands of walkers, all led by The Queens Guide to the Sands who until last year was Cedric Robinson MBE who held the position for as long as I can remember.
I was born and raised in the area and the sands of Morecambe Bay can be very treacherous so if any of you reading this find yourselves there please do not stray to far from the seafront and certainly never, ever attempt to undertake a cross bay walk without the official guide since the safe route can change very rapidly.
