Hi Roger,
Her are some answers to some of the questions and confusions.
Gustav Carl Wilhelm's children were:
Emma born Nov 21 1863 in ST Petersburg , Russia - died Feb. 21 1863 Oberhambach Germany
She married Nov 15.1883 Peter Heinrich von Witt in St Petersburg
They had 3 children
Robert (my grandfather) born in Pau, ( he is the only one not born in St Petersburg, as my great grand parents did a spa vacation in Pau at that time) France Dec 13 1864 died Sep 9, 1945 in Berlin
He married June 26 1895 Anna Katharina Schroeder (my grandmother)
They had 5 children , one of which is my father
Adolf Theodor was born May 11 1867 in St Peterburg died April 22 in 1928 in Buenos Aires.
Was married twice first with Charlotte Amalie Erlenbach 0n October 7, 1888 in Frankfurt.
They had one child
second marriage was with Auguste Studt September 22 , 1896 in Berlin
They had 6 children , all born in Argentina except Erwin and Nora.
Erwin was born in Berlin, Wilhelm, Amalie, and Electra in Cordoba, Argentina and Robert in Rosario Argentina and Nora in Reinickendorf , Germany
I do have the information on their children as well but nothing more about the next generation. Effort to track done the living generation in Argentina failed so far.
Back to Russia.....
The fourth child of Wilhelm and Emma Elben was
Wilhelm Elben born Feb. 18, 1870 died 1. quarter of 1919.
Married June 27 1896 Olga Revillon in St Petersburg (Olga was born Feb 10 1877 in St.petersburg and died in 1936) By the way her father was Albert Revillon an ingeniuer in St. Petersburg, hence her name Oga Albertovna (Olga from Albert)
They had 5 daughters and one son Wilhelm, all born in St.Petersburg. Wilhelm and his children adopted Russian citizenship.
We know that some of them and their children died during the second world war during the German occupation of St.Petersburg. One of these sad examples where members of the same family fought against each other!
There are some relatives still living in Russia today but I do not have a detailed knowledge.
The fifth child was Olga born October 17 1874 died Nov 11 1885
The sixth child is Hedwig born Sept. 30 1876 also in St. Petersburg died May 18 1883
The seventh child is Alfred born Nov 15 1877 died Dec 09 1955 in Jugenheim Germany. He was married twice with first
Margarita von Greim-Nilsky 1902 in St Petersburg . They had two children.
Margarita and Alexander. I had the previllage to get to know Margarita (nickname Nicky) several times, while she was still alive. She died in 1989 in Hamburg. Her children and grandchildren live in Switzerland, UK and Germany.
Second marriage with Elisabeth Hedwig Schroth wedding Sept 24 1908 in Danzig
one child
I do have more information on these guys (Elbens) but unfortunately all written up in German.
The Argentine part for me is also interesting because I am sure there will be young generations existing nowadays in Argentina. By the way my father told me Alfred had to leave Russia because he had some affair with a woman and started as a cowboy for Libbys in Argentina?
The reason why you saw sometimes Stuttgart instead of St Petersburg as the birthplace is the following: A lot of the family in formation was written up in the 30 and 40, partly during the NAZI regimen in Germany. In those days it sounded better when you were born in Germany and at the end of the war they kept the birthday Stuttgart in fear of the approaching Russians. My father e.g. had also a passport that said that he was born in Stuttgart but he was clearly born in St. Petersburg.
So here is my father:
Robert Georg born Jan 20 1911 in St.Petersburg died Wiesbaden March 24 1992
Married to Sophie Agnes Lina Heyl April 19 1944
Two children, My brother Georg Robert born 1945 retired DMD , lives in Bamberg Germany
and myself born 1950 like my brother in Erlangen in Germany living in Sarasota, FL
I have two children, Andreas , born 1986 in Somerville, NJ and my daughter Sandra born 1984 in Wiesbaden, Germany. Both my children live in Germany
Keep me posted if you can find out something about Argentina. Also if you need pictures of Emma Brofft let me know. My tel is 941 923 7983 and may be we chat one of these days.
