Especially Juliette's family

First of all, his father, Jules, or Julius Sohn. No paper ever gives his date or place of birth.

He would be Alsacian, but I learned not to trust the family tradition - or legend, better to say -. I wonder whether he would not be born in one on the german territories that were french departments under Napoleon.(Bade, Rhenan Prussia, Palatinat... ). He was born around 1807 and made a carrier in french army.

The clues :

• His daughter's name, Frederika, typically german.
• In the convoi in 1848 (the 15th), he his flag-bearer. That position was given only to former soldiers.
• He married a french girl, Mélanie Boutmy, they would have made the wedding in the Vienne department (in garrison?)
• He died, may be in Algeria, according to Juliette on the 23rd of July 1856.But his death is not listed in the Archives of Aix-en-Provence that get all the civil records from our former colonies.
  

 The three Koiransky brothers who emigrated to the States :

• Alexandre Koiransky, Social Security card n° 061-12-1909, issued in New York before 1951, he is born on 21st of February 1882 in Saint Pétersbourg,and died on 4th of December 1968 at Palo Alto, son Arnold Koiransky,and of a lady born Delasyy. .
• His brother Henry-Gennadi, Social Security card n°134-18-1205, doctor, who arrived in New York after having lived in Berlin. He worked in a hospital in Manhattan. He was born on 31st January 1881, also in Saint-Pétersbourg, and died in September 1981, at San Diego, California.
• A third brother, maybe named Eugen, or at least a brother of Gennadi, listed on New-York'S census. He might be dead quite early, too early to get a Social Security card, or he left the States, because he is not listed in the beneficiaries of Social Security Cards... Or, but I donÄt believe it, he is still living.

And two women, maybe spouses :

• Marianne Koiransky, born Desroches,on 5th of Aprill 1890, died in May 1981, at Palo Alto (Card n°552-21-9126)

• Rose Koiransky, born on 24th December 1884, died in May 1964, againin California. (Card n°140-20-7692)

I asked for the copies, conforming to regulations and costs, but did not receive any answer. I think their father, Arnold, was a cousin or an uncle of my great-grand-father Haim, maybe even his father having a second spouse..
