His great-uncle, Benjamin Langlois, sponsored Tom's legal studies at Lincoln's Inn, London.

But as to our having ever met, except at the three last balls, I cannot say much; for he is so excessively laughed at about me at Ashe, that he is ashamed of coming to Steventon, and ran away when we called on Mrs. Lefroy a few days ago.. .

The latter is really very well-behaved now; and as for the other, he has but one fault, which time will, I trust, entirely remove – it is that his morning coat is a great deal too light.

In the letter to her sister, Austen writes that Tom's aunt Mrs. Lefroy had been to visit, but had not said anything about her nephew... "...to me, and I was too proud to make any enquiries; but on my father's afterwards asking where he was, I learnt that he was gone back to London in his way to Ireland, where he is called to the Bar and means to practise.

[5] Upon learning of Jane Austen's death (18 July 1817), Lefroy travelled from Ireland to England to pay his respects to the British author.

Serjeant Lefroy and Mr Saurin have been… re-edifying their Orange disciples in Dublin with much curious but rather apocryphal twaddle, touching the coronation oath, the Act of Settlement and so on.The learned Serjeant expresses his hostility to the proposed law by declaring that he is averse to the removal of ancient landmarks.

Now, if the saintly Serjeant means that the letter of a law can constitute a political landmark, we can assure him he is in pitiable error.Lefroy may have been influenced by Huguenot family memories of persecution by French Catholics; this was the case with other opponents of Catholic emancipation such as William Saurin mentioned above.

[10] Tom Lefroy continued to represent the university until he was appointed an Irish judge (with the title of a Baron of the Exchequer) in 1841.

Despite some allegations in Parliament, that he was too old to do the job, Lefroy did not resign as Chief Justice until he was aged 90 and a Conservative government was in office to fill the vacancy.

One apocryphal story (in the memoirs of the Home Rule MP JG Swift MacNeill) describes Lefroy's son as denying in Parliament that his father was too old to perform his duties, but being himself so visibly old and feeble as to produce the opposite effect on parliamentary opinion.

Another version of this story has the son defending his father's capacity although he himself had applied to be excused certain official duties on account of advanced age.

In a satirical pamphlet on the Trinity College Dublin election of 1865 Joseph Sheridan Le Fanu suggests that Lefroy was so old that he had "ridden on the mastodon to hunt the megatherium" and mocks the manner in which the Conservative lawyer-politicians Joseph Napier and James Whiteside allegedly insisted whenever the Conservatives were in power (and might appoint them to replace him) that Lefroy is too old to perform his duties, only to insist whenever a Whig government is in power that he is in perfect health.

The planet Jupiter, which through an ordinary glass is no larger than a good star, is seen twice as large as the moon appears to the naked eye.

It was all true what Doherty [a Chief Justice, more than six feet high] said, that he walked upright in the tube with an umbrella over his head before it was set.

The telescope weighs sixteen tons, and yet Lord Rosse raised it single-handed off its resting place, and two men with ease raised it to any height.According to the website of Carrigglas Manor at the Wayback Machine (archived 2 February 2003) (Tom Lefroy's house in Longford, Ireland), the Lefroy family came from the town of Cambrai in the northwestern corner of France.

In 1765, Tom's father Anthony Peter Lefroy was secretly married to Ann Gardner in Limerick, Ireland.

[11] From their marriage, they had seven children as listed in the Visitation of Ireland:[14] Another son (Benjamin, born 25 March 1815) died in infancy.

James Gandon the famous architect of Dublin's Custom House designed and built a stable block and farmyard and walled garden for Lefroy.
