Last native Cornish speaker

Supposedly, the last fluent native speaker of the Cornish language was Dolly Pentreath, whose house still stands in Mousehole. Bob and I totally missed the site the one time we were in Mousehole and I was determined to find it this trip. Some accounts say Dolly was the last person who spoke only Cornish, while others say she learned English at the age of twenty. Regardless, Betsy and I found the house!
