FERNEBOK/FERNEBOCK family in Warsaw ans France #france

Tamar Weinblum

I am searching for information on Henri Fernebok/Fernebok born in Warsaw 1928, son of Yosef Fernebok b. 1905 in Warsaw and Ester Lesgold b. 1907 Warsaw.
The family immigrated to France around 1930 and was settled in Paris.
Yosef perished in 1942 and Ester with 3 children survived. 
In Mai 1948 Henri Came yo Israel as a volunteer With the "MACHAL" , he was killed near Jerusalem 20.10.1948.

I am looking for his date of birth, the name of his paternal grandparents, and the siblings of his father.
Thank you
