Hi Diana
Amy had no occupation listed in the 1911 census and Arthur was listed only as a worker. The father was a tailor. Ancestry has little or no isle of man records. The UK census is all you can find unless the person emigrated to the USA, Canada or Australia. the family is found in the 1901 census as mybrea, transcription error. I posted the correct name, so you should be able to find once ancestry prossess the submission.
