Hi Michael
Because of the dates you mention, the burials/cremations are likely to have been in municipal cemeteries and Bereavement Services is usually the first port of call as they generally hold the records.
As you have found though, our hobby can have a detrimental effect on their work-load so many do charge for look ups.
It varies so much, in the last week or so I have sent emails to 3 cemeteries depts about half a dozen burials, each time giving name, date of death, address at time of death and the responses have varied wildly
1 Emailed a cemetery in Delaware about a burial in 1912 - was utterly gobsmacked to get a reply , complete with cemetery map, telling me the section and plot number within TWO MINUTES. No charge, just a lovely reply saying they were pleased to be able to help. I emailed right back to express my thanks and delight for their help
2 Emailed the cemeteries dept in Edinburgh (repeatedly) each time I got section, plot number and a map with the correct area marked. Lovely lady who was so helpful and pleasant and couldn't help enough - no charge - I emailed back to express my heartfelt thanks.
3 emailed North Tyneside Cemeteries about two burials, got a reply within the hour which said they would be happy to look for me, at a charge of £10 per person, payable in advance. I haven't replied, its not the fault of the person who told me the charge, probably not even the fault of the local council who feel they need to make the charge but its way outside my budget and I just can't think of a suitable reply.
