Oh, I know that sounded ridiculously vague. I meant that I was looking for some sort of social history resource, a general accounting of why people immigrated from France mid-nineteenth century, not specifically whay my family immigrated.
However, these are my mid-century French immigrants:
Louis Aloncle b. 1822 Married 1850 in France in U.S. 1860 (per census) occupation optician
Enlisted as Civil War soldier Sgt. Philadelphia Pennsylvania 1861 mustered out same year
Spouse: Rose Jeanne Marthe Vila b. abt 1828 with Louis on the 1860 census; listed as wid. on 1870 census NYC. I do not find her on the 1880 census.
I know that two of their children were born in France:
Marthe Aloncle abt 1853
George Aloncle abt 1854
The next child, Louise Josephine, is born in the U.S. in 1857
I am assuming that the family immigrated between 1854 and 1857.
I am wondering why they would have immigrated in terms of the political and social climate of France at the time.
Thanks for responding.
