Nancy: Yesterday I reviewed my newer info re Hubeners; aw your message from Jan 2001. Newer info:
NYC Directory 1890:
Herman G. Hubener machinist, h. 585 E. 136th
Henry Hubener, grocer, 833 Ninth Ave.
also, Brooklyn, Ny directories:
Henry Hubener, cooper, 421 S. 5th Brooklyn, NY 1889, 1890.
Hope this helps; perhaps you have already discovered some of this.
