谁和Isabella Ingram-Seymour-Conway, Marchioness of Hertford约会过？

Isabella Anne Seymour-Conway, Marchioness of Hertford (7 July 1759 – 12 April 1834) was an English landowner and courtier and a mistress of King George IV when he was Prince of Wales. She was born at Temple Newsam in Leeds, and was the eldest daughter of Charles Ingram, 9th Viscount of Irvine, and his wife Frances Gibson Shepheard Ingram. She married Francis Ingram-Seymour-Conway, 2nd Marquess of Hertford, in 1776, at age sixteen, being his second wife. She was known as Lady Beauchamp until 1794 when her husband succeeded his father.

Isabella was co-heiress to Temple Newsam along with her four sisters, and owned properties in Worcestershire, Norfolk, Ireland and London.

Tall, handsome, and elegant, she caught the attention of the Prince of Wales most likely at a ball or concert at Manchester House, the London home of the Hertfords. George was also friends with Isabella's son, Lord Yarmouth, born in 1777. In 1806, the Hertfords became guardians to Mary 'Minney' Seymour, a favourite of the Prince. Charles was made Master of the Horse in 1804 and a Knight of the Garter in 1807.

At first, Isabella rejected George's advances, causing him to become depressed. He made a visit to Isabella's mother at Temple Newsam in 1806 whilst attending Doncaster races as an excuse to see Isabella. George became obsessed with Isabella and became ill when parted from her so that the Hertfords travelled to London to see him and George was miraculously cured. In 1807, Isabella, now almost fifty, began a relationship with George who was then in his mid-forties. As a result, the Prince was a regular guest at Hertford House, Hertford's London residence, and Ragley Hall in Warwickshire. A Tory herself, she was influential in turning the Prince toward the Tories and away from the Whigs, and used her London residence as the headquarters for Tory sympathisers. Isabella was criticised by the House of Lords and in the press for her influence on George; satirical prints by George Cruikshank and others were produced.

The Marchioness's predecessor as the Prince Regent's mistress had been Maria Fitzherbert, a Roman Catholic. Other Catholics disapproved of the Marchioness's influence over the prince, referring to "the fatal witchery of an unworthy secret influence" that they felt had turned him against the idea of Catholic emancipation. George Canning, speaking for the party in power, made use of these comments to say that, if Lady Hertford was really responsible for the prince's political decisions, she was "Britain's guardian angel". Isabella made a point of humiliating Mrs Fitzherbert and by 1811 the Prince had formally separated from her.

On the death of her mother in 1807, she inherited Temple Newsam in West Yorkshire, where the Prince of Wales had paid her a visit. She and her husband added the name of Ingram to their surname due to the fortune they inherited from her family. Lavish entertainments were held at Hertford House attended by the Prince, members of the royal family and visiting nobles, including for victory celebrations in 1814. Isabella's dresses were reported in the press including a Greek-style ostrich feather head-dress worn in 1813 styled on the Prince's crest.

Lady Hertford's relationship with the Prince, now prince regent, ended in 1819, when he turned his attentions to Elizabeth Conyngham, Marchioness Conyngham. According to Greville’s diary for 9 June 1820:

Somebody asked Lady Hertford if she had been aware of the King's admiration for Lady Conyngham, and whether he had ever talked to her about Lady C. She replied that 'intimately as she had known the King, and openly as he had always talked to her upon every subject, he had never ventured to speak to her upon that of his mistresses'.

Isabella continued to spend the season in London, but otherwise lived at Temple Newsam. Here she busied herself with charitable works, being the patron or member of many events and societies, and was noted for her benevolence to the poor as well as her generosity to the servants at Temple Newsam who held an annual ball and supper in the house. Lady Hertford died in 1834 after catching a cold on her way from Temple Newsam to London by carriage. Her obituary in The Leeds Intelligencer described her as 'Her intellectual character, and high attainments, formed the least part of her excellencies; however enlightened her mind, her heart was warmer still. To the poor and the distressed her munificence was all but unbounded'.

喬治四世（英語：George IV，1762年8月12日—1830年6月26日），全名乔治·奥古斯都·弗雷德里克（英語：George Augustus Frederick），1762年至1820年擔任威爾士親王，1811起因父王喬治三世患精神病而兼任攝政，1820年1月29日正式繼位為聯合王國國王和漢諾威國王，直至1830年6月26日駕崩。

喬治四世平生沉醉奢華生活，他引領英國攝政時期上流社會的時尚潮流，並熱衷支持新興的休閒、潮流和品味。他曾委任知名建築師約翰·納西在英國海邊旅遊名勝布萊頓興建規模宏大的皇家穹頂宮，又重新裝修白金漢宮、委託傑弗里·威雅維爾爵士重建溫莎城堡等。他對倫敦國家美術館和倫敦英皇學院的籌建也有重要影響。

在家庭方面，喬治不單與父王交惡，與髮妻卡羅琳的婚姻更是如同災難。1820年事先透過國會引入極大反響的《痛苦和刑罰草案》，企圖與卡羅琳離婚，結果不但失敗，還廣受抨擊，1821年加冕時還下令禁制卡羅琳出席大典。

政治上，喬治任攝政後，大部份時間均由利物浦勳爵擔任首相。在喬治甚少過問朝政的情況下，英政府帶領英國於曠日持久的拿破崙戰爭中取得最後勝利，並與各國商定戰後的和平秩序，還試圖應付一系列的社會和經濟動盪。喬治晚年被迫接受與他不和的喬治·坎寧先後出任外相和首相，以及放棄一直以來反對天主教解放的立場。

雖然喬治的風采和品味為他贏得「英格蘭第一紳士」的讚譽，但他與父王和妻子的惡劣關係，以及放縱奢華的生活，使他受到平民百姓的蔑視，王室尊嚴也因而受損，很多納稅人更對他戰時的窮奢極侈感到憤怒。在國家陷入危機的時候，不僅沒有擔當領導國民的重任，生活上也沒有成為國民效法的楷模；不少朝臣也認為喬治四世為人自私、欠缺誠信且不負責任，一生深受弄臣影響。
