Looking for a list specific to New York City to contact about NYC info second half of nineteenth century.  

Specifically seeking information about a club, or society, known as the "Bavarian Central K. U." as noted in an obituary dated 1889.  Desire meaning of initials, purpose and repository, if any, of records.

Please advise if you can suggest a list (or digest) to subscribe to, or info about the Bavarian Central K. U.  Thank you.
