Please Help - A Spuffy Story

[debris4spike]

I thought I was fairly organised - with the stuff I have on my pc .... but ... can't remember the name of this story.  So I don't know whether I have it archived - or where to start looking.  Hope you can help it has been bugging me for ages -

Buffy and Spike have 2 young visitors form the future arrive ....and later a 3rd.  All girls - who turn out to be 3 of their 12 (I think) kids.  The only other thing I can remember is that the girls are named after relatives - including Dru'

Hoping this rings some bells
