Traditionally, Builders and Joiners were also undertakers.
Having been in the timber and building trade for over 45 years, I remember it was mostly the case, and certainly in surrounding villages.
Back in 1977 after Trenery's were taken over by May & Hassell, I was offered the managers job at one of their most outlying branches, a small timber merchant they had just taken over in Wigton, Cumbria, and 40% of their business was the sale of coffin boards to builders.
Needless to say, I turned it down, and am still in Boston. Wigton looked a right mess on a wet and windy day.
