After going thorough the various novels that have mentioned other slayers preceeding Buffy's calling, I decided to try my hand at putting together a timeline that named all the slayers, their watchers, and the timeframe in which they were active. These dates are only approximations. Sometimes only staring dates were declared, or the slayer's death was marked down, but not her length of service. While I intend to go back and tweak the exact times at some poing, for now I've simply filled in the years that I remember from the books. I'll be adding more names later as I re-read the novels.
