I am looking for biographical information on Gustaf Nybom, a Finnish sea captain, born in Oulu, who became a head of the Alaska Commercial Company in the late 1800s.
I could find this information about Gustaf Ferdinand Nybom (Niebaum).
I am sorry, but he was not born in Oulu but in Helsinki on August 30th 1842.
The source of information is NIEBAUM-COPPOLA WINEYARD HOMEPAGE and the adress
I could find another article on the Internet and the adress is:
There is one publication about Niebaum-Coppola Winery.
The title of the book is "A SENCE OF PLACE : AN INTIMATE PORTRAIT OF THE NIEBAUM-COPPOLA WINERY AND THE NAPA VALLEY" by Steven Koplan and Francis Ford Coppola. Routhledge, 1999. ISBN 0415920043.
I hope, this information makes it possible for you to continue your work.
