I appreciate your interest.
As a side note....I believe Jeanne (my great grandmother) was born in Italy. At some point, and I do not know the timeframe, she emigrated to Buenos Aires. I just recently found out some incredible information recently. My grandmother, was not her biological daughter.
Armand Lagneau (Laino in the 1895 Argentine Census) was in Buenos Aires with his wife, son. And that is where my grandmother was born.
According to a US passport application for my grandmother in 1920, she listed she returned to France in 1916. In a 1920 French marriage certificate my grandmother lists her biological mother as "absent"....which may be interpreted as "divorce"? Possibly then her father, Armand came back with Jeanne Tosi as his wife? Maybe he met her in France after 1916? In 1929, Jeanne Tosi Lagneau makes a trip back to Buenos Aires from the USA with her step daughters grandson. Must be to visit relatives?
