Gerken in Wangerooge

Does anyone have any information about a H. Gerken who operated a hotel at Wangerooge in the 1920's? I am trying to find descendents of this person as I am building my GERKEN genealogy. Thanks for any help. judithafair@hotmail.com

There is still today a Restaurant Gerken, address:

  Gaststätten, Restaurants Strandrestaurant Gerken Fax +49 4469-1464
  Peterstr. 13
  26486 Wangerooge Nordseebad

it has a conection to "Upstalsboom Strandhotel":

This Hotel was former "Strandhotel Gerken" since 1891.
