I thought access to stuff like Registry House was still paid access? maybe not.
Other than Ancestry, other place is the Mormons — Family Search I think it is — but you’d have to double check the records that they give as results..
I took a good deal of research on part of my family – Stirling – as done by a couple of uncles and cousins, and followed that further, filling in details, to generate a family tree. I used that detail to fill in the other 3/4 of my ancestry, on my other grand parents that didn’t get the full treatment, and found a heap of interesting stuff, great aunts that my mum didn’t know about, tracing mum’s family back to darkest Accrington & Haworth..
