Was having a browse through Danbooru. Found an interesting chart showing how some of the characters relate to each other whether they be from another series in the Type-moon universe. It managed to wrap up a few uncertainties I had lingering between Kara no Kyoukai and Tsukihime as well as Fate/Stay Night and Fate/Hollow Ataraxia (since there is no English translation for the game yet). Hope this chart was helpful to others as it was for me.
