The document talks about the Ashford family tree, and the first person mentioned was Veronica, a woman. I'm not too sure (because it's been a while since I've solved that puzzle), but there was only one painting with a woman in it, so you push the button on that painting. Then it goes on and on and you have to follow the clues. Example: The document said something like "[Insert Ashford ancestor's name here] passed down the family tea cups to [Insert another ancestor's name], who had twins." So, you look for the portrait of an old man with tea cups (or WHATEVER the document said -- I don't remember exactly) and push the button on his painting. Then you look for the picture of a man holding twins and push the button on his picture, etc etc etc.

you're walking down a hall that looks strikingly similar to the hall in RE1 (the one where the dogs popped out) and that huge worm busts through the wall twice, just like the dogs in RE1.
