This peak is usually referred to as St. Charles Peak, I have no idea why they don't label it as such on topo maps, but when locals say they're going to the top of St. Charles Peak, everyone knows what they're talking about
I've lived in Preston most of my life and I've always known the peak above Bloomington Lake as St. Charles Peak. http://www.summitpost.org/saint-charles-mountain/313115
Some people call FCHP "The Felt Hat" But I've never heard anyone refer to it as St. Charles. They're always talking about the peak mentioned above when they do.
