Heerema - Ritsema oorsprong
Hello Dennis,
   I hope all is going well for you and your family and that you are happy in your new position. I am not sure whether I have finished playing with it yet but I have added the latest version of  my obsessive genealogy behaviour. I will probably add more graphics and detail. My first version was corrupted and I had to start over and this is one of the reasons I am sending it now, to prevent any more angst about losing what I have done to date. If you have it also I can always get it forwarded back.
   Thanks again Dennis.
