[1] He is best remembered for the lengthy court battle which ensued after his death, lasting over twenty years, exhausting the finances of many of his kinsmen, and shocking much of Welsh society.
[5] In 1730 he was described by the rural dean of Merionethshire as "a profligate, young rake, who, not withstanding, affects gaiety of dress beyond any woman".
[1] Despite living mostly in London, in later life, he exercised his responsibilities as a squire in Merionethshire, serving as a Justice of the Peace and High Sheriff in 1724 and in 1736.
[4] In North Wales, he was friends with Sir Watkin Williams-Wynn, 3rd Baronet, who granted him the Freedom of the City of Chester on 20 November 1736 (during which year he was Mayor) and Giwn may have shared his Jacobite sympathies and may have been in his Cycle Club of the White Rose.
[8] Giwn died in 1776, aged 77, and was buried in Llandrillo Church, where there is an elaborate memorial to him (now hidden behind the organ, due to the influence of the Passinghams who were later Churchwardens of the parish).
[9][dead link] Giwn Lloyd had apparently had an illegitimate daughter by Elizabeth Taylor, a bar maid who worked at the Thatched-House Tavern in St. James's.
Hendwr had been continuously owned by the same family since 11th century and suddenly a man with no connection to the area or people had seized the estate and ejected a 91-year-old spinster from her home – Richard Hughes Lloyd writes pathetically, of Mr Passingham, "God forgive him".
In 1807 John Lloyd of Gwerclas received an anonymous letter informing him that the decision of the Shrewsbury Assizes had been obtained by forgery and he began a new notice of ejectment against Jonathan Passingham.
