Is there anyone who has information regarding Louisa Katharina nee Keller, HEIL of Jablonowka (Russian village name), Laube (German village name), or Lauwe (American village name)? She was born abt. 1794, married Johann Adam Heil born abt. 1799; died about 1855. They had 3 sons: Johann Michael born abt. 1820, Johannes born abt. 1822, and Heinrich born about 181825 in Lauwe. I am interested in the descendants of these 3 sons.
