There is a Jan Heijwegen b. 16 February 1903, listed as dying 12 April 1948 it lists two wives to him:
Wilhelmina Smit, b. 1908, married 1930, marriage ended 12 Jan 1948, by divorce (door S = door scheiden)
Hannah Livadaros (
), b. 2 August 1918 Mynddislwyn , married 18 Feb 1948, marriage sadly ended the same year, 28 Jul 1948, when she died (door O = door overlijden).
There are four children listed between him and Wilhelmina, between 1928 (before the marriage!) and 1940. One stepdaughter b. 1938 Amsterdam with the surname Janssen (?) whose parentage is uncertain, and then the two daughter b. Cardiff - a marriage date and husband's name is given for the younger.
There is a card for "Hannah Livadaros" which also makes a reference to "Ann James" - it only lists her marriage to Jan and her two children with him who we already know about.
Her birth *is* listed as Livadaros and there is a marriage for her parents (under Liadaras or Liaderes). Her father, Sivionas Liadaras, was born in Greece in 1892
I'm guessing either her mother remarried a Mr James and she took that name later, or the name was changed to sound more English.
