" Augustus Miller, Q north cor 21st west (1865)
August Muller, 71 21st west (1866)
Notes:
I'm thinking that "Augustus Miller" and "August Muller" are the same guy. The 1866 directory lists him as both a bottler and a brewer, so I guess he made beer.
The 1860/1870 census lists an August Miller as being born c.1814 in Germany, but it lists his occupation as a gardener, so I'm not sure if it's the same guy." From.
