Hendrika Kokernoot was the 2nd wife of the bread baker Abraham Frieser, who had seven children with the then 19-year old Roosje Melkman in a first wedlock in 1907. Roosje Melkman, a daughter of Hartog Melkman and Judith Granaade, was born on 22 January 1888 in Amsterdam and passed away 20 September 1926 in Rotterdam.
Hendrika, the 2nd daughter of Matthijs Kokernoot and Mietje Gompers, married 4 March 1936 – 40 years of age – in Amsterdam the 50-year old widower Abraham Frieser, who was born on 9 March 1885 in Rotterdam as son of David Frieser and Christina Susanna Bekker. On 27 November 1936 their only son Matthijs was born. After the wedding in Amsterdam Hendrika and Abraham went living in Rotterdam, at first in the Nieuwe Rubensstraat 37b but they moved on 1 September 1938 to Oranjeboomstraat 329a in Rotterdam.
On 10 April 1943, the Frieser family was carried off from Rotterdam to Westerbork, where they were accommodated in barrack 57. Ten days later, on 20 April, they were put on transport to Sobibor, where Abraham Frieser, Hendrika Frieser-Kokernoot and their son Matthijs on arrival on 23 April 1943 immediately were killed in the gas chambers there.
