I also have a rudimentary family tree linking them all, but it is so unfathomably huge (9m x 6m) I don't quite know how to present it. Version 1 with randomly-coloured nodes is here. Version 2 with country-coloured nodes is here Moreover the type of computer language-trees that are normally seen in such circumstances are in no way accurate maps: nothing less than a 9-tuple can show the complexity of computer language inheritance. However, the record for each language will show the relationships in a navigable format. Please be patient when downloading them as even the small ones take a while to create.

A list of my own favourite languages is here. Some links to further resources (including other HOPL sites, and several language genealogies) are here. An elementary reference bibliography is Here.

This effort is dedicated to Jean Sammet, pioneer and visionary, without whose tireless efforts most of this information would have been lost forever.

Any changes and corrections should be adressed to myself, Diarmuid Pigott (dpigott), at the University via email (@murdoch.edu.au). (I used to have a direct link, but it got harvested)

NB: This resource is built to be seen using a laptop/LCD display using IE6 and Cleartype. I know there are people who use other systems, and I am sorry if this is difficult for you. I am using facilities that IE has which other systems don't, to maximise the amount of information I can get on a screen.

PS: in answer to the latest comments regarding selection, I quote Strachey:
I am all in favour of having lots and lots of programming languages. Of course, most people who write a complicated large program for dealing with some kind of group of problems are in fact writing the program language. I think that when we know more about writing compilers, more programs will look like languages instead of multiple-purpose subroutines. I must say that the fact that business languages started off by being ever so simple, and then got unwieldy and complicated, does remind me of the early computing machines which were going to be "ever so simple" to program.
