<p>We live on one of the streets in the group mentioned by the OP. My D applied to that school and I remember wondering if it would cause any amusement in the admissions office. I can report that in any event there was no measurable boost in admissions success.</p>
<p>As to how they came to be so named, I have no idea and I'm a real estate agent when not living on-line or writing. And the streets do encompass both West L.A. and Santa Monica.</p>
