Now that I have this info, how to I find where they are from in Germany?

Positive Findings:
Naturalization - KELBLE, George date Nov. 3. 1904. Birth date March 16, 1866. Arrived in NY on May 24, 1892. Address 155 W. 108th St., NYC.German (This address matches their address on the 1910 census).

Ship: PENNLAND from Antwerp to New York. Arrived May 24, 1892. KOBEL, George 26 Labr; Wife Theresia 28; child Anna 1yr. 3 mo. (another daughter {Rose} is not listed she would have been a few months old).

Ellis Island findings: KOLBEL, George. Ethnicity - BAYERN with ship Pennland and arrival date as listed above with wife and one child.

I know that BAYERN is BAVARIA, Germany. Now I need {{{HELP}}} as to where to go from here to find them in Germany. Also, wanting to locate living relatives before my Mom who is suffering with cancer dies.

BTW, I've always known them by the KOELBL spelling. Thanks in advance for your help.
