Where Are You?

I cannot find Ruby Water (b. 1911) and Vary "Mack" Huyler (b. 1903) in the 1930 census and it's very frustrating!

Mack's parents are still at home in Lexington Co., SC and Ruby's are in place in Atlanta. But where are their children? In only a few months, Mack and Ruby will be married in Atlanta. But where are they in April of 1930?

There is a Ruby Waters (b. est 1912) listed as an inmate at in the Georgia State Penitentiary. I wonder....
