Mark was born in Towednack, Cornwall in 1796.  In 1816, he married Mary Broad in Redruth, and shortly after moved to Brecon in South Wales. They had a son, William Humphrey Broad Berryman, but Mary died shortly afterwards. In 1831, Mark married a widow, Margaret Charles, and had seven children: Henry, Matthew, Margaret, Sampson, Elizabeth, John and Robert. They lived in "The Struet" in Brecon, and Mark's occupation is listed in the 1835/1837 Pigot's Directory under Shopkeepers & Dealers in Groceries and Sundries, and in the 1851 Census of Brecon, he is described as a "currier".

This photograph was dated between 1884-1891, taken by a Brecon photographer, Henry Hobbis.  It is believed to be of Mark and Margaret.  Alan Berryman discovered the photograph in the effects of Mark's great-granddaughter, Gladwys Goldsworthy ("Auntie Daisy"). I have not yet found Mark in the 1861 census; but if the photo opposite is indeed of him, we can assume that he made it to at least 1884 (88 years old).
