What you stated above seems to be the general consensus. Most if not the majority of Spike fanfic writers and essayists have determined he had sisters (possibly three - no idea why that number) and a father who either left them or died.
There is evidence in the series that leads one to believe this was the case. His relationship with both Dawn and Willow. How he handles women. Men raised with sisters - tend to be better with women for some reason or more comfortable with them, I've discovered. Also it fits with the fact that Buffy got involved with Spike after Dawn's entrance into the plot. Whedon has a tendency to like to parallel character relationships.
So I think you're theory above is probably what happened.
