Hi Werner,
Maria Katherina Henriette Eschen was born 26 Aug 1847.
She married Ferdinand Nuxoll in Effingham County, Illinois on 26 Nov 1867,
only 4 months after arriving in USA.
And no, I haven't done the specific search you suggested on LDS. I'm not
quite sure how to do that online. The only thing LDS shows online is
that she married Ferdinand.
Marlies from Bieste said she would see if she could find any records for me.
Thanks again for your suggestions,
Angela
