I am not new to genealogy but new to trying to research the birth sites and available records in Germany.

My ancestors were reportedly born and lived in Bayern, Germany before immigration to the United States (New York) in 1837.

Arriving in 1837 on ship Ann was
George Hoffmann, aged 45
Marguerite Hoffmann, aged 43
Christian Hoffmann, aged 17
Jacob Hoffmann, aged 14
Christine Hoffmann, aged 12
Mathias Hoffmann, aged 8

My ancestry tree listing them can be found here:

I need help in trying to figure out what part and city of Bayern they immigrated from.

I have the birthdate of only Christian, who was born Feb 12, 1820. He is my direct ancestor.

Any suggestions on where to start this kind of search would be appreciated
