The Joseph Jacober I know of is the grand father of my grand father. He was born in 1818 and died in 1890 in the south of Alsace (either Wittersdorf or Altkirch, I'll check out). His wife Anne-Marie Meyer went to the USA in 1853. She was in Loretto in 1853 and later on in New-York about 1890. She died most probably before 1900.
