He married c. 1887 Annie Louisa Gormer and had at least four sons and two daughters of whom there are descendants living in England and Scotland.
It is possible that when his father received British nationality that they changed their family name – Dommershuizen – into the more English sounding surname Dommersen / Dommerson.
Dommersen painted between 1875 and 1927 genre pieces, landscapes, marine scenes, village- and town-scenes of quality.
He painted mostly in the Netherlands and England but visited also, often with his father and uncle, Belgium, France and Italy.
At some stage he lived in Royal Tunbridge Wells Kent, which was strategically placed for his travels to Europe.
