John Swan his son, born in 1870, followed in his father's footsteps and carried on the business after the death of James in 1905, changing the name to John Swan, Monumental Sculptor.

John had two sons Jonathan and Douglas who trained and continued in the business, which became John Swan & Sons. John died in 1943 leaving the two sons to carry on in the business. The brothers decided to part Company in 1957, Jonathan trading as Jonathan Swan Monumental Sculptor and Douglas as Douglas Swan Monumental Sculptor. Sadly Jonathan died in 1961 leaving only the business of Douglas Swan to carry on in the family name.

Douglas junior joined his father in 1970 and in 1974 the firm became Douglas Swan & Son. Ian the younger of the two brothers became a partner in 1980 and the current name of Douglas Swan & Sons was established. Douglas senior died on 1982.

Douglas junior's younger daughter Carrie joined the firm in 1999 and Ian's elder son Jamie started work in the family business in 2003 making them the fifth generation of Swans to work in the memorial business in Kirkcudbright.
