He was born in the parish of St Martin, on the Channel Island of Jersey, second son of George Bandinel by his second wife, Elizabeth Lempriere.
He was sometime Chaplain to the Marquess of Buckingham, the Viceroy of Ireland, and his nomination to a bishopric had been proposed by his close friend, Viscount Bulkeley of Cashel, with whom he travelled in his youth.
He sold off his possessions in an auction from his home in New College Lane, Oxford, and moved with his young family to Dorset.
Bandinel’s memory was long cherished at Netherbury, with a respect and devotion which had not died in fifty years after his death.
Bandinel married in December 1775 to Margaret Dumaresq, and had five children, of whom Mary Anne, born 1784, died at the age of fourteen.
