DNA testing for genealogy continues to improve. If you had some of your Koepka relatives tested several years ago, it may be worthwhile to have them retested. Likewise, as DNA testing companies have gathered more results and samples, you may be able to find more matches if you search again with your test results.
2003-06-30: the World Wide Web was invented by Tim Berners-Lee and Robert Cailliau in 1990. In 1989, while working at CERN (the European Organization for Nuclear Research), both men made proposals for hypertext systems. In 1990 they joined forces and wrote a joint proposal in which the term World Wide Web is used for the first time (originally without spaces).
The first web browser was invented in 1990 by Sir Tim Berners-Lee. Berners-Lee is the director of the World Wide Web Consortium (W3C), which oversees the Web's continued development, and is also the founder of the World Wide Web Foundation. His browser was called WorldWideWeb and later renamed Nexus.
