This mansion/museum is located in our town. We didn't attempt an investigation, but we did visit at Christmas time and took some pictures. Award winning and built in the 1800's,is this 26-room mansion of
elegance. Superbly carved oak fretwork, butternut and hand-carved wood
mantels are just a few of the finely crafted features inside. It's architecture is Romanesque and it contains 26 rooms and a third story ballroom and beautifully decorated in period furnishings.
Flash cameras are not permitted, so orbs that were caught (and there were many) are probably valid. Here are some of the better ones.

I believe this was in the sitting room

This is one of the display rooms, but is actually the kitchen.

This is the ballroom. Note the ectoplasm on the left in front of the bandstand.

I just wonder how many people have taken pictures here and seen anomalies through the years.
