I believe I have two Kannenberg lines in my genealogy. First I was a Kannenberg and have this line back to my gggrandparents. Posen, Germany.
My gg grandmother was Rosalie Kannenberg, her daughter, Wilhelmine Caroline m. August Edwin Kannenberg. Does anyone have any idea of how I can find more info on Rosalie?

Rosalie b. 1837 in Witowono,Bromber,Posen,Germany
Wilhelmine Caroline b.6 Jan 1866 Schmukalle,Bromberg,Posen,
Germany
m. 16 Feb 1890 Allentown,Leigh Co., Pennsylvania
August Edwin Kannenberg b.25 Oct 1864 Schmukalle,Bromberg, Posen,Germany
Don't know for sure on when Wilhelmine Caroline came to the USA. August Edwin came in 1890 and ended up in Allentown, Leigh Co., Pennsylvania.
Any help would be appericated.
