Thank you, both
Will look-in on FindMyPast.
It seems a few Registers have not been filmed.
Just had a reply from East Yorkshire re St Marys [Scarborough] ...
"294 (Brass) Here lieth interred JOSEPH / HOOD who died the 12th October 173(-)aged 53 years"
"TPR 173(-) Not found in Register"
If East Yorkshire are correct that they could not find this Joseph Hood interment in the [burial] Register, it seems the Memoral plaque is the only record.
When death Civil Registration started in 1837, some felt that complied with the Law and some Burial Registers stop. However, when a new Law came in, in 1858 even more Registers were handed over to the Registrar General, which went to the P.R.O., now in the TNA, Kew, RG series.
Kind regards, Mark
