At the beginning of 1910, the then 53-year-old Snouck started a relationship with 36-year-old Ida Oort, daughter of Abraham Oort, former minister of the Reformed Congregation in Zutphen. They got married on 8 July and their daughter Christien was born in December 1914. She ended up teaching classical languages in Leiden and kept her father company on his deathbed in 1936.
