Can we make isoglosses?

"Mich" does seem to be a vaeriant of Milk in SW-Germany. The Voll-mich reference is clearly linked to Vollmilch.
Even more interesting if you search 'mich' you find two expressions:
Kaufmich -> merchant

Zwingmich -> stubborn person

In both cases '-mich' stands for Michl which stands for -guy
While not Austro-Bavarian at all, it could indicate 'gaismich' in the Herzogenburg document is indeed the goat-guy which would make sense regrading the reference in the St. Pölten Urkundenbuch for 'Geisiunge gans' - goat-boy. It would mean the same thing. Geese to be paid for the services of a goatherder. Though 4 geese per year for a goatherder seems excessive.

It also doesn't make sense in the VM-context as goatherder and frankly I have a hard time rooting this expression in the South Alpine region. I tried to find more '-mich' expressions in documents from monasterium.net but there are tons of entries for the usual meaning 'me'.
