Stegmann from Rosenfelde West Prussia

Hello,

I'm looking for more information on this family:

Friedrich Stegmann who married Caroline Keinitz
Two of their children came to USA
Albertine Eurma
Johanna Bertha

Albertina reports being born in Rosenfelde, West Prussia, Germany Sept 9, 1875
Johanna Bertha was born Nov 7, 1870

I would like to know birth dates and places of births for them & their parents and any other brothers/sisters, if possible.

Thank you to any one who may be able to help.
