One couple from Northampton were left stunned after they found a hidden note hidden inside their wall, which was written 70 years ago.

Karl Church and his partner Eve Jones now hope that they can track down the author's descendants.

The note was written by a John Rainbow in 1953. It was discovered by Karl, 49, after he decided to install patio doors in his home, reports Northants Live.

The note read: "Bricklayer rate 3/6 ½. February 17 1953. J. Rainbow, 122 Kingsland Avenue, age 50."

Eve, 48, shared a photo of the incredible note on the Northampton Photos and Social History Facebook page in the hope of finding Mr Rainbow's relatives so that they could return it to them.

She said: "My boyfriend was having the back window knocked out in one of the downstairs rooms.

"When that was being done they found this tin in the wall with the note in.

"He was thinking should he go knock on 122 Kingsland Avenue but the chance of the descendants being in that house are minimal really.

"It was put in a drawer and forgotten about it but he got it out the other day and decided to find the original descendants of Mr Rainbow.

"I popped it in the Facebook group yesterday and it has attracted quite a bit of interest."

They now hope that they can track down the author's descendants

Several members of the Facebook group worked out that the note belonged to a John W Rainbow who was alive from 1902 to 1993 and lived at 204 Birchfield Road East between 1939 to 1946.

He was wed to Lillian Luck, and the couple shared two daughters together - Phyllis, born in 1925, who later became Mrs Green and Iris, born in 1926, who became Mrs Mills.

It's thought the couple now have several grandchildren born in the 1950s and 1960s.

Eve said the couple were living in Birchfield Road in Abington where she happened to have grown up.

She said: "John William Rainbow was born in 1902 which tallies with the date because, on the note, it said he was 50 years old and it was written in 1953.

"He seems to have had two children but no sons. He worked for London, Midland and Scottish Railway company and was a bricklayer employed by them."

A clipping of a newspaper that showed that Mr Rainbow won more than £2,000 on the football pools which his daughter Iris filled out for him was also shared by a user of the Facebook group.

The article stated Iris' fiancé, Wally Mills, would "give her a kiss every time she checked a box" - leading the family to win a prize.

Eve admitted she doesn't like posting in groups and thought it would be ignored, however said she was overwhelmed with the response.

She added: "There do seem to be quite a few Rainbows around Northamptonshire."

Despite pinpointing John Rainbow, Eve said that unfortunately none of his relatives have come forward yet.
