In 1925 she is listed as operating both as Grocer and Post Office.
Winifred Spoor tells us:
The main shop in Heddon was run by Mrs Waugh. Her first shop was in Haddock's Hole, in the middle house. On the Military Road side of that house was a pantry window and on the lintel above the window in red lettering was the word, 'Lemonade'. After school time there would be a member of the family perched in the pantry window to sell lemonade and sweets to passing cyclists. Mrs Waugh moved to her new shop at the Old Post Office, further west on the opposite side of the road, which she bought from the Sir James Knott estate in 1924.
36) In loving memory of John Waugh died Nov 1909 aged 50 years. Also Mary Ann wife of the above died 1 May 1955 aged 86 years. Also Grace Ivy daughter of the above died June 1903 aged 1 year. Also John son of the above accidentally killed in British Columbia April 1927 aged 30 yrs. Also Isabella Knott sister of the above John Waugh (senior) died at Toronto Canada June 1948 aged 78 years. Also William Andrew Waugh son of the above died 17th Oct 1968.
Mr Waugh who when we first arrived in the village ran the Post Office. This was a small shop that sold everything from groceries to vegetables and bread. His sister Violet worked as a post lady and delivered our mail through all weathers. It was not until she retired that I was aware of the size of her round. Not only did it cover the older part of the village along with the Military Road and Houghton but also all the outlying farms towards Ponteland. I remember that the Newcastle Journal ran an article when she retired and they calculated she had walked some 1/4 million miles delivering the mail. No doubt today it is done by a man-in-a-van in half the time but lacking that personal touch.
