August Adrian was my great grandfather, also. From the book "Germans to America Volume 14" they were listed as: Wilhelm (male age 53), Wilhelmine (female age 50), Carl (male age 27), Marie (female age 26), Fridch. or Frederick (male age 21), Carl or Charles (male age 19), Ferdinand(male age 18), Adolph (male age 16), Franz or Frank (male age 14), August (male age 7) and Ernst (male age 5).
August's father was Frederick Wilhelm Adrian and his mother was Caroline Wilhelmine/Amelia Fehling. So a switch in names at the time of immigation?
An earlier posting has F. W. Adrian married to Bertha Trettin in 1867. This was his son Fredrick William Adrian the second and he passed away in Belgrade MN on February 14, 1918.
