BOLLING, Henry b Hannover 1860 > 1879 TX

Can anyone help me?

HEINRICH F. BOLLING was born in the KINGDOM of HANNOVER around 1860.
At age 17, he immigrated from Bremen on the "Neckar" arriving in the
port of New in August 1879. His parents did not immigrate. The ship's
manifest lists only "Germany" as his birthplace/residence.

Do you have any idea as to how I should go about identifying HEINRICH's
birthplace? Thank you.
