John Carsten Schierloh married Catherine Beisler (Beisner) in 12-5-1866 in New York City certificate 4519. I have the certificate. Her father was Martin Luther Beisler and her mother was Anna Loceife b. Bruns.
All the rest of the documents say Beisner.
She was born in Osterholf, Hanover.
According to her census record she came over in 1865.
This is what I can read of the documents.
Since I know some of your documentation was lost in the flood, I have found some certificates.
I have not yet found Henry Beisner, however, that does not mean he wasn't there.
