Hi Jenny,
I have the GRO Marriage Index entry for your grand-parents:
GRO MI Q4 1925 ECCLESHALL, Louisa (spouse LYONS) Liverpool 8b 351
and possibly the index entry for her birth:
GRO BI Q4 1902 ECCLESHALL, Louisa Jemima W.Derby 8b 589
Does the age of your grandmother when she died match this possible birthdate?
If so I have several other records of ECCLESHALLs relating to W.Derby around 1902. So they may be relatives too...
If your grandmother was not born around 1902 tell me her age when she died and I will check again as I have other Louisas but not Louisa Jemimas!
Do you know your Louisa Jemima's parents names?
Hope I can help some more.
Regards, Mike Wheatley
