According to his wife, the couple had no known contact with anyone with coronavirus.
After an autopsy confirmed he had Covid-19, Mary Matthews shared a photo of her husband on a local Facebook page, in the hope people would recognise him.
She also advised people to self-isolate if they have been in contact with him.
Speaking to Nailsea People, she said: "People who may have come into contact with either Nick or me during the past two weeks need to self-isolate and get advice.
"Although he tested positive, until a post-mortem examination, we can't say that was [the] cause of death at the moment.
