hello from Paris
thank you for your answer
1) I do not know when they do in Ufa neither when they arrived
2) henry is born in 1920 in Ufa : does that mean it is available to ask to the civil authorities ?
3) they were in strasbourg in 1924 when my mother is born : I do not know what they do between
4) I wrote to the two adresses you gave me ; thanks again
thanks a lot
