I think the cemetery on the corner of Dill hall Lane and Queens Road West was known as Clayton Cemetery.
Although there is a cemetery attached to All Saints Church.....but I do not think that is the one.
I think that maybe the Library in Accrington would be the best place to seek out some of these answers....there are people at the library who have the expertise to research these issues.
It may be worthwhile e-mailing them Ann....or maybe a phone call.
They can be reached on this number. 01254 872385.
Their e-mail address is

I hope this will provide you with the help to find the answers
