[Qgis-user] georeferencing maps

[Firstname Lastname]

hello
i am trying to do some basic georeferencing.  i have been using the
georeferencing tool and i have been following the workflow suggested on
youtube files using the georeferencing tool
i have tried three different maps of new and old vintage.  i have tried to
keep it simple with 4 points control points and have used as many as 10
points.  when i apply the georeferencing, my maps are not calibrating.
even the control points end up 400-600 m. of off the true coordinates.  Any
suggestions that might help fix this.
for reference, i used the epsg 3857 CRS
