I want to (belatedly) conclude this thread by summarising the key information that has been so kindly provided in answer to my original question. Some of the info has been communicated off-line, so I felt it appropriate to update this Rootschat record so that it might help future Banks researchers who tread this path.
My original query sought to determine whether the Willenhall Archive reference to the death of Thomas Banks and his wife was in respect of ancestors of mine. The Willenhall Archive says "An application on behalf of Charles Foster, in whose house Thomas Banks and his wife had died from Cholera, for 2 blankets to replace those destroyed was received and Mr Isaac Tyldesley was requested to supply them."
Thanks to death certificate information provide by Stephen, I now know that the couple were Thomas Banks (b 1784) and his wife Emma (nee Hadley, born 1788 and shown as "Amie" on her christening record). Thomas and Emma Banks are my 4x great-grand parents. They died together, on the same day (31 August 1849), of cholera. The circumstances of their death are very poignant.
I had originally hoped there would be a local memorial in Willenhall, listing all those who died in the 1849 cholera epidemic but, judging by the responses I have received, this appears to not be the case. Perhaps the local council will one day do something about it - but I guess there are always other priorities. I hope to visit Willenhall and the cholera cemetery at some time in the future.
In conclusion, I would like to thank Stephen and all the other respondees to my original question.
Regards to all
Bill Banks
