V. Relatives of the La Rochefoucaulds.
The surname of De Ponthieu is worthy to be associated with the most noble names. Messire Charles De Ponthieu, a refugee officer, was married to Marguerite de La Rochefoucauld in London at the Church of Les Grecs, 7th October 1691. She had a brother, a resident in Portarlington, named Reuben de La Rochefoucauld. To that town De Ponthieu retired on a captain’s half-pay. The children of Captain and Madame de Ponthieu were Henry and Josias, and a daughter, Mademoiselle E. de Ponthieu, who was married to Major-General Cavalier. Josias was named after Major de Champagne, who was his godfather. The fact of Madame Cavalier being a relative of Madame Champagne, accounts for the interest which the distinguished Major took in her, and for his great liberality to her and her husband in money matters.
