I don't understand why you are modeling it that way. Why have the
ReferenceProperty in Location?
Given your case of wanting all people with a given birthplace, it
seems like this makes sense:
class Person(db.Model):
name = db.StringProperty()
birthplace = db.ReferenceProperty(Location, default="unknown",
collection_name='born_here')
class Location(db.Model):
place = db.StringProperty()
Since a person is likely only born in one place, you put the reference
with the Person.
Now you can do:
birthplace = my_person.birthplace # gets Location
and
some_location.born_here # list of Person born here
