Teunis Kooijman, son of Dirk Kooijman and Magdalena de Kuijper, was born on 20 January 1868 in Giessen-Nieuwkerk and died on 11 July 1937 in Jutphaas.
He married Cornelia den Ouden, daughter of Abraham den Ouden and Bastiaantje Kortlever, on 7 August 1913 in Groot-Ammers. She was born on 15 July 1871 in Groot-Ammers, and died on 7 August 1961.
Teunis previously married Bertje van Es, daughter of Cornelis van Es and Aaltje de Jongh, on 31 August 1892 in Tienhoven. She was born on 5 april 1866 in Tienhoven and died on 28 September 1910 in Jutphaas.
Teunis Kooijman and Bertje van Es had at least two children. As far as I know, Cornelia den Ouden did not marry previously and did not have any children. The text onze lieve moeder (our dear mother) on the tombstone is probably from her stepchildren.
Teunis and Cornelia are buried together on Kerkveld cemetery in Nieuwegein.
