I have found related spellings as
Schmidgall, Schmidtgall, Schmitgall
Schmittgall, Schmithgall; and these
with one or two "L" variations. I am in
search of all Schmidgall spellings and
tree history for worldwide Family genealogy
gathering at Minot, ND USA. There is no
charge for attendance; special rates and
location of events upon request.
