To confuse you even more on 28 June 1785 at Glossop church Samuel Furniss marries Ann Lingart
He is of the parish of Glossop and signs the register. She makes her mark and I can’t decipher where she is from. It might say if the parish aforesaid.
I found the actual image by ploughing my way through the register book on Ancestry.
If it was my family I’d make 3 trees up from the Glossop and Chapel en le Frith registers of the Simpson, Lingard/t and Furniss families. I’d go from around 1720ish up to 1820ish. That way hopefully you’ll make sense of what is going on.
I’d use the actual parish registers which are on Ancestry and do one family name at a time, extract all those of that surname and build a tree. I’ve done this myself with a confusing family, I ended up with lots of post it notes and physically built trees on the floor before importing them into a family tree programme.
Then take the next name and do the same and so on. Hopefully the links between the two families will become clearer. Maybe also have the OS map for the area so you can see where the families are living.
