In the last few days of 2001, while surfing the web, I came across a web-page created by James (Jelle) Kooistra. On one of his pages (that happened to be written in Frisian, but which I could understand sufficiently to get the gist) he mentions that he had been asked to translate a paper from Old Dutch into English concerning the origins of the Couperus family and John Cowper who fled from Scotland. I wrote to him asking about this paper, and in a subsequent reply he enclosed a fascinating document. What he sent was a computer-generated document created by an application (HAZA-DATA from Telepas Software) that retrieved its information from a genealogical database containing information that Jim had entered originally. It contained a lot of obviously carefully researched data - including dates and places of birth, marriage and death. The data he sent me was originally created in researching another family tree which however had some of its roots overlapping the Couperus tree. Thus while it only provides a part of the latter, it is nevertheless a substantial part that provides valuable extra information. This new information includes both some people who are not mentioned in the original stamboom of Meester Couperus at all (such as female members as well as some males who were missing) as well as details about dates and places of both the new and the already-known entries. I have updated the detailed indented "Stamboom" with some of the information he provided, but because of the way that page is organised, with each entry limited to one line on the screen, I could not include much of the finer details such as places of birth and additional narrative. But this information could be of inestimable value to other Couperus researchers and I wanted to make sure that such researchers would be able to find that information here. Accordingly, I took Jim's original document and (after removing some entries that were concerned only with "the other family" whose tree overlapped with the Couperus tree but were otherwise irrelevant to the Couperus tree) I reformatted the information suitable for presentation on a web page. I have included in blue the generation/slot numbers I used on the "Indented Stamboom" page for purposes of cross-reference. But because many entries are completely new, I had to assign them new numbers, thus they do not appear necessarily in simple numeric sequence but jump around quite a bit. However I have maintained the style of indenting children under their father to allow readers to more easily see the family relationships. My thanks to Jim Kooistra for providing this wonderful addition to our knowledge of the Couperus tree. I can heartily recommend a visit to his web site at http://www.geocities.com/jkooistraca/ Be sure to visit his "Roots" articles if you can read Frisian (absolutely fascinating for those who enjoy languages, word origins, and etymologies) but even if you don't, he also has a wealth of other links on his pages to other sites involved in Friesland and Genealogy. My web representation of "The Kooistra Document" follows below.
