  We apply in a novel fashion a modified semi-classical method to the Bianchi
II and VII$_{h=0}$ models when a cosmological constant, aligned electromagnetic
field and stiff matter are present. Additionally we study the non-commutative
quantum Bianchi II models when an aligned electromagnetic field is included.
Through the use of the Euclidean-signature semi classical method we find a
plethora of new solutions to these model's corresponding Lorentzian signature
Wheeler DeWitt equations which we can interpret qualitatively. These new
solutions for the aforementioned models involving matter sources reveal some
potentially interesting effects that should be chronicled as possible phenomena
that a toy model of quantum gravity can induce on the evolution of a quantum
universe. Furthermore we find 'excited' states which behave differently from
the 'excited' states of the Bianchi IX and Taub models that were previously
uncovered using this method. By comparing and contrasting the 'excited' states
given by these models we help facilitate a better understating of what
constitutes an 'excited' state solution of the Wheeler Dewitt equation. Our
results further show the utility of the Euclidean-signature semi classical
method for tackling Lorentzian signature problems without having to invoke a
Wick rotation. This feature of not needing to apply a Wick rotation makes this
method potentially very useful for tackling a variety of problems in bosonic
relativistic field theory and quantum gravity.
