Warburtons

Thomas Warburton and his wife Ellen first opened their grocery shop in 1870, but it wasn't until 1876 during a slump in the grocery market when Ellen Warburton started baking bread. Ellen's first batch of four loaves of bread and six cakes sold out in under an hour. Within two weeks, the tiny shop in Bolton was renamed "Warburtons the Bakers" and continued to go from strength-to-strength ever since.
