Notes:
Ernest Ott Rammel was born April 28, 1873 in Germany, and came to America in 1890. The 1919 directory indicates that William L. Rammel was the General Manager. I think William L. was born 1884, so he was probably Ernest's younger brother.
The 1920 directory lists the Whistle Bottling Co at the same address as the Rammel Mfg Co. Likewise the 1921 directory lists the Christo-Cola company at the same address. So my guess is that these companies were either owned-by or working closely with the Rammel Mfg Co.
