Dear Karima, I have checked many Stickan families from Germany and have not found Hans Stickan or Johanne Heinrich Stickan.
My grandfather, CHRISTIAN GERHARD ADDICK STICKAN was born or christened on May 5, 1868 in Golzwarden, Brake. (I have a goopy of his christening record from the church there.) His father was FRIEDERICK HEINRICH AUGUST STICKAN, born in 1828 in Dielingen, Westfalen. Many other STICKAN families were from Destel, Levern, and other nearby towns.
I cannot find a connection. However, you may want to contact LORA STICKAN JONES, who lives in southern Indiana. There are Stickan families there, but I have not found a connection to them. Lora's e-mail is email@example.com
. She would probably like to hear from you. Good luck with your search. Do you live in Brake?
