My direct line ancestors were in the United States by 1898, but I did find a couple of uncles who remained in Germany in these directories. Some of the entries for Wrisse are shown in this post, Johann and Jurgen Goldenstein are brothers of my ancestor Focke Goldenstein.
Also shown in this post are some of the entries from Holtrop (the left hand column of page 1341). Eilt Ufkes was a brother to another ancestor, Johann Ufkes.
The images are searchable at Ancestry.com. Most of the entries have to be searched by last name only.
