Thank you so much for this info!!
I was able to locate a grave I've been seeking for ages on deceasedonline. Ancestry, findagrave ect don't list it at all so I've had no luck in the past. Thank you!!
Glad this helped someone else out

!! Yes, I would definitely recommend trying all sorts of tricks that you can on Ancestry, including wildcards (* or ? to substitute many or one character), or just using a first name or a last name (whichever you consider most likely to be misread) and a county/municipal area and a year or year range (say if a person's death is registered in December, they might be buried any time between September or January the next year).
Also, as I said, bear in mind a lot of places that used to be in counties are now part of cities, i.e. Birmingham includes what used to be parts of Warwickshire, Staffordshire, Worcestershire etc., and they will be listed under those cities and their district or borough names on deceasedonline, which you can put in the keyword search (don't put district/borough in the place search box).
