It is likely that early in his life Beato and his family moved to Corfu, at the time part of the British protectorate of the Ionian Islands, and so Beato was a British subject.
Ketika masih kecil, Beato dan keluarga tampaknya pindah ke Corfu yang waktu itu bagian dari protektorat Britania di Kepulauan Ionia, sehingga Beato adalah warga Persemakmuran Inggris.
