I'm trying to help a 70+ year-old-friend find something about her natural father, Charles Brooks of Gladwyn Co or Genesee Co (Flint) Michigan. In so doing, I've searched for the street my friend says she lived on in 1930 -- Riverside Drive in Flint. Does anyone know of a map that shows the Enumeration Districts for this census? Actually, this type of map could be very helpful for lots of researchers . . . but do they exist? Thanks for any ideas! Jean Edwards in California
