I sent you and email directly, but in case others have a similar interest, here's a summary of my connection to the Hasenzahl Family.
My great grandmother is Elizabetha Hasenzahl. I believe she was born in Frankfurt in 1854, but the family is more likely from Alsheim.
I believe her parents are Johann Michael Hasenzahl and Maria Catharina Dutine.
She arrived in New York in 1873. I know of two brothers Henry (1857) and John (1859) who also came to New York – both were barbers. There is another possible brother, Joseph (1866), and a possible sister, Catharina (1868).
Elisabetha (also known as Lizzie and Elise) married John (Jean) Schuller – they raised a family of eight children in Brooklyn New York. Henry Hasenzahl and John Hasenzahl also married and had relatively large families in New York and New Jersey.
