We have finally cataloged all the old pictures and named who is who in them. I have managed to scan the pictures of Henry Postma and Dr. Gerard Postma. And the siblings of my grandfather: "Kees" and "Kiek." The Ekama book written by Henry Ekama my great great grand father, is being translated in to English. And an additional volume is in the works.
Also as far as we have been able to tell our name means "the guy around the corner." Interesting, thanks to Napolean. Also due to him our name has been spelled different ways Ekama being the most common. Though if you look on most searches you will find none. Napolean has also caused the Postmus name to be changed to Postma.
I am trying to track down information on Klaas Postma, and many others that are 5-6 generations into my tree. Those of which include Cornelius Ekama, Knoop, and Verburg.
I have found more descendants of Klaas Postma thanks to those on the Genforum.
The Cincinnati Lloyd Library and museum has a book/ encyclopedia of scientific people written by the medical Dr. Cornelious Ekama
The is a road named for him in Haarlem.
