DIAMANT and KAFKA families

We are searching for the families of
JUDr. Jiri DIAMANT
and
Marianna KAFKA (KAFKOVA)

they were two of the siblings

We have learned that JUDr. Jiri DIAMANT worked for (presumably the Czech government in exile), for the Supreme Accountancy Controlling Authority.  On 5 Feb 1943 he was in London and headed the Ministry of Foreign Affairs in Fursecroft, George Street London, W.1

We have found at Yad Vashem in Jerusalem possible links to the family in the form of people who submitted Pages of Testimony for members of the family who died in the Shoa, see the attached 1977 POT for Karel.  I cannot at the moment make out who it was that submitted this.

Do you recognize any of these names?

Can you guide us in any way?

If you have no information, do you know of anyone else, anywhere, where we can ask?
