i need to learn how to research these ancestors:

Peter BRAUER
Birth abt 1797 in Hesse-Darmstadt
his wife
Elisabeth Carl
Your 4th great grandmother
Birth 1802-1806 in Hesse Darmstadt

no arrival data found yet, but they have a daughter in baltimore, MD in 1823 so that sets an upper limit.

her maiden name is provisional, i have reason to believe
her nephew is
Charles Carl sr
Birth Sep 1825 in Hesse-Darmstadt
he arrives in baltimore in 1849

i'm also looking for
Johann Friederich Klanke
Your 4th great grandfather
Birth abt 1792 in Hesse-Kassel
and his wife
Catherina Margaretta Agnese Kloecker
Birth 1794 in Hesse-Kassel

they arrive in baltimore
