Obituary: Louisa May Alcott (页面存档备份,存于互联网档案馆), New York Times, March 7, 1888. The obituary indicates that the family moved to Boston when Alcott was 2 years old, therefore in 1834-5. This is supported by the United States Census, 1850 which records that her younger sister, Elizabeth, was born in Massachusetts and was aged 15 (therefore born around 1835) at the time of the census.
