Do You Know The Way To…Doelger City?

I was looking up directions on Yahoo Maps last night (last-minute driver’s license renewal, blah). While looking at the map I noticed that Yahoo Maps thinks there’s a neighborhood in SF called “Doelger City”. A little Googling reveals that at one point, the Sunset district was mostly built by a guy named Doelger and at one point it was known as Doelger City. Does anybody use this term today? I wonder where Yahoo unearthed it?
