Hello Bernard, I don't know if it's too late to ask you if you could help with my family dilemma. Is it possible to look up Pavel I Ratner and Julia Rattner or Ratner at 6 Rue Lincoln 8th Arond 75008. I have little further information . They left St Petersburg around 1917 due to the revolution and I have this address. Pavel (Paul) was born in 1859 in Belarus. His wife Julia nee Rosenstein was born in Constantinople. They had 2 daughters whose names were Xenia and Alexandra( Sasha) who may not have been with them. I doubt were living with them . I would be very grateful to you . Best Wishes, Patricia Lane Sydney Australia
