I found about 3 in the area ( not Armitage Bridge) and checked them all on the Non Conformist records list for West Yorkshire Archives and none had early records listed so presumably they have been lost and they didn’t send them to the Registrar General in 1837 as those would also have been listed.
It may have been for convenience on the part of the Lees family. The children I found all married in the C of E ( I didn’t look for them all) and some appear to be buried in the local C if E like their father.
I think you may have to accept that you won’t find baptisms but maybe concentrate on tracking them down and finding other descendants, you never know someone may have a family bible.
I’ve found the Quaker book but it refers to Wooldale, High Flatts and Midhope. The Quakers kept good records and they are available online. I will have a read through the book over the weekend.
I like NLS maps too but I used Huddersfield Exposed website to find Heygate and my 1987 1:50,000 OS map Sheffield and Huddersfield to get an overview of the area. It’s extremely battered from having spent a lot of time in my rucksack with my Dark Peak 1:25,000 maps from my Peak Park Ranger days
