You are being sought by Rachel Withers who has a £50 cheque for you to collect.
The cheque - compensation from a well-known UK high street bank - was sent to Mrs Burbidge's former address in Trowbridge.
Miss Withers, 58, said: "I am staying with my 94-year-old mother during lockdown and opened the envelope in error just before Christmas.
"It is dated December 11 and I opened it more than ten days ago. I would like to find Mrs Burbidge so that I can hand it over to her.
"Clearly, the bank which sent it has not got her current address. I have been told she has moved to Hilperton."
