This reminded of a book that I read a while ago. It listed the important ideas that lead to modern computer science in a chronological manner[1]. Is there any work done to trace the genealogy of computer science like [2]?
Depending on your definition of `Computer Science', [2] is already the link you're looking for. Church, Turing, von Neumann, McCarthy, Shannon and many other founding fathers of Computer Science are there. In fact, from your link, I believe the only people mentioned who are not in the Mathematics Genealogy Project are Lovelace and Boole, and that's because the PhD system didn't really exist in England at the time, so a specifically Computer Science based database wouldn't help with that.
