We are trying to find ancestors of Henry Kasten who was born in Hannover, Germany in 1825. He married a woman by the name of Elizabeth Bruning(Bruening)born around 1836 also in Hannover. They must have been married in Hannover since their first son Henry was also born in Germany. They emigrated to America sometime before 1859 when my great grandmother Anna Kasten was born in 1859. They settled in St. Louis Mo. Any help on this would be appreciated.
