Attestations from sources in English:
nehmotloConles (normally, nehmotloConlis) = are to ring on my behalf
The standard form would be nechmotlaocoliliz. The missing "a" is apparently a reflection of pronunciation in this area and time; it was typically missing in testaments from San Bartolomé in the early-nineteenth century.

Tlocolia was a standard variant of the valley of Toluca around the time of Independence.
