Is there any historical evidence of the gifts of healing in operation by the second Century? I was wanting to know if any of the church fathers have documented anything concerning the gift of healing with eye witness testimony or the gift of Miracles being in operation by the second century?
Yes, The Martyrdom of Polycarp records the following event (occurring circa AD 155):

And as the flame blazed forth in great fury, we, to whom it was given
to witness it, beheld a great miracle, and have been preserved that we
might report to others what then took place. For the fire, shaping
itself into the form of an arch, like the sail of a ship when filled
with the wind, encompassed as by a circle the body of the
martyr...those wicked men perceived that his body could not be
consumed by the fire (see chapters 15-15 here).

This event was:

Observed by numerous people (public execution of a Christian Bishop)
Recorded by an eyewitness shortly after the event
Related by a group (Christians) that at the time lacked significant political or
economic power (in fact they were a persecuted minority)

It's pretty hard to get away with a fabricated story--let alone publish it all over the empire--when those three things are true.
