The following is what he writes about Isabel Darcy:

Isabella was the ninth daughter and thirteenth child (of Edward Darcy) was born about 1600. She was married about 1619 to John Launce of Penneare in St.Clement's, Cornwall, son and heir of Robert Launce of Penneare, by his wife Susan, daughter of George Tubb, of Tringoff, Cornwall. John Launce was born about 1597 (aged 23 in 1620 Visitation of Cornwall.) John Launce, described as a parliamentarian died of a wound received in an altercation. She was married for the second time, as his second wife to Rev. Sydrach Simpson, Master of Penbroke Hall, University of Cambridge. He died in April 1655, and was buried at St. Bartholomew's Exchange, London where he had been rector. She died testate at London in 1669 (will dated 29 May 1668, proved 4 Aug 1669, mentions her daughter Mary Sherman).

David Faris states his sources for this paragraph as:

American Genealogist 20:129-135 (Jan. 1944)

American Genealogist 21:169-177 (Jan. 1945)

This court case would have either been concluded just before or around the period of Johns death.
