18Lart: Lived in the parish of St. Peter-le-Poor, Dublin, died suddenly in London, 12 Jan 1772.

15[BBB]: “Became a wine merchant in Portugal, no doubt engaged in the port wine trade, in conjunction with the family wine importing business in Dublin. He was in the Lisbon earthquake of 1755, and survived, contrary to mistaken reports that a Charles had perished. He was a signatory to a memorandum to King George II, and a petition to the Secretary of State in London, from British merchants in Portugal, asking for assistance to put their affairs on a sound footing again. The answer is not known.

On the front of '1754', the account of the family compiled that year, there is an entry signed 'Chas. Boileau' stating that a very full account of the family, written in his father's hand, was partly burnt in the fire which followed the earthquake.

He was appointed a Director of the French Hospital, London in 1768, and d unmarried in London 1772.”
