The Vicomte David d’Ully de Laval's stepdaughter, Marie Louise Charlotte (de Cobreville)de Laval , following the family’s return from France to Portarlington in 1751, would marry Gilbert Tarleton of Portarlington.
Gilbert Tarleton was the direct descendant of Gilbert Tarleton who had been born in Hazelwood, Lancashire, in about 1580, and who died in 1656 in Geashill, Killeigh, King's County - his grandson Gilbert Tarleton married Elizabeth Warren and would die in Portarlington in 1740. Their son, Edward Tarleton (1708 - 1740) married Anne Tarleton, and their son was the Gilbert Tarleton of Portarlington who married Marie Louise Charlotte de Laval in the early 1760s.
The Killeigh and Portarlington Tarletons were related to the prominent Tarleton family of Liverpool.
(The register of the French Church in Portarlington also records the death in Dublin of another elderly Tarleton family member, Elizabeth Tarleton, aged 68 on 15th January 1797.)
On August 1767, the couple had another son, David Tarleton. Present at the baptism were Samuel Beauchamp, merchant of Portarlington whose daughter, Martha, was the second wife of Thomas Willis, and Miss Francoise de Laval, aka Frances or Fanny, the daughter of David Daniel de Laval.
Yet another son was Henry Tarleton who was of the military and who died in action.
A daughter of Gilbert Tarleton and Marie Louise de Laval was Henriette Tarleton who married Gideon Castelfranc IV, a lieutenant-colonel in the English army who died childless in 1839. Gideon was the son of Francis Castelblanc and was a member of a noble family of Castelfranc, near La Rochelle, whose surname was De Nautonnier, and who had fled to England at the time of the Revocation.
The head of the family at the time of their flight from Catholic France was a cleric of La Rochelle, married to Marguerite Chamier. They had three sons and six daughters, three of whom, following a spell in captivity in France, had been released and settled temporarily in Geneva. The other six children had been en-route to a penal settlement when their ship had been captured by the English who brought the Castelfrancs to London. One of the daughters married a Mr. Testas, another a M. Boudet. Three of the sons entered the English army - two died in action, while the third later settled in Portarlington.
The son who settled in Portarlington on a half-pension from the army of William of Orange was Gideon/Gedeon Castelfranc, who had married Marie Pin and who died in Portarlington on 11th July 1749. This was an ancestor of Gideon Castelfranc who married Henriette Tarleton, the daughter of Gilbert Tarleton and Marie Louise de Laval.
The earlier Gideon Castelfranc was the brother of Abel Castelfranc of Rathbone Place, Marylebone, London, whose will was probated on 22nd July 1748 and who had married Suzanne Le Blanc. Abel's will confirmed that his brother was Gideon Castelfranc who had settled in Ireland and who held a lease of mortgaged land at Siskin, Queen's County; Abel had financial interest in these lands and mortgages and decreed that, following the death of his brother Gedeon, that the land should be divided equally between Gedeon's three sons, namely Peter, Francis and Gideon. Peter was named as Abel's residual legatee and was the man who proved the will in London in 1748. Also named was Abel's sister, Mary Nautonnier Castelblanc who was to benefit from his will provided she continued to keep a school. A niece was Esther Castelblanc who was to receive South Seas annuities; a niece in Ireland was Charlotte Dolier; a third niece was Margaret Castelblanc; a fourth niece was Charlotte (?Bessott) of Switzerland. Abel's late brother-in-law was Albert Le Blanc who had left him his plate and linen, and which Abel was now leaving to nephew Peter Castelblanc. Peter's wife was named as Abel's niece, Elizabeth Castelblanc, the wife of Peter.
