Lotspeach... Most likely Lotspeich!

Per: http://www.rulen.com/partisan/roster.htm

Lotspeach, William >Quantrill
Had a farm on Sugar Creek, near Wadesburg, Cass
County. On July 10, 1862, Maj. James O. Gower with
a detachment of 1st Iowa Cavalry, and 65 men from
the 7th MO Cavalry under Capt. William A. Martin
from Harrisonville, along with 63 men from the 1st MO
Cavalry under Capt. Martin Kehoe attacked the
guerrilla camp nearby. Killed 1863.

Is there any additional information readily available on the Lotspeach?
[I have a few Lotspeich in my database... These would be allied to my families.]
