I am looking for information regarding Johann Hinrich SIEBELS and his family who resided in Fedderwarden, Oldenbürg, Germany in the early 1900's.
He married Louisa Maria Henrietta Wilhelmina REINERS.
Hinrich Gerhard ONKEN was born 4/29/1881 in Heidmühle, Schortens, Oldenbürg, Germany to Jürgan Gerhard ONKEN and Gratja RADEMACHER. He married Rieke Tiebbend SIEBELS, daughter of Johann Hinrich SIEBELS and Louisa Maria Henrietta Wilhelmina REINERS. Rieke was born 3/26/1886 in Belfast?, Bant, Rüstringen, Oldenbürg, Germany.
They came to Illinois in the summer of 1910 and moved to Minnesota in 1912.
I have information on Hinrich and Rieke's children, but I would like more information on their parents and siblings/half-siblings.
