Born: about 1760 and died 23 January 1833 and buried Presbyterian, Gateacre, Lancashire.
Son of: Joshua Crompton (171?-1770) and Elizabeth Colthurst (17??-1778).
Brother of:
1. Thomas Crompton (1759-1781).
2. William Crompton (1761-1769).
Peter married: 20 March 1787 in Chorley, Lancashire, Mary Crompton (1757?-????) daughter of John Crompton of Chorley Hall.
Peter and Mary had issue:
1. Edward Crompton (1788-????).
2. Mary Crompton (1789-1825).
3. Emma Crompton (1792-????).
4. Henry Crompton (1792-????).
5. Stamford Crompton (1793-1830).
6. Caroline Hutton (nee Crompton, 1793-????).
7. Sir Charles Crompton (1797-1865) who married Caroline Fletcher (????-1882).
8. Albert Crompton (????-1841).

My knowledge of Peter Crompton comes from:
1. Information supplied to me by Sheila Howells who has researched this from many sources including the Crompton Papers in the Derby Local History Library.
2. Information supplied by Darren Harris regarding Maplewell Hall.
3. Various mentions in James Caldwell's diaries relating the the Brewery business.

I assume that this Peter Crompton is the Dr Peter Crompton of Eton Lodge (now Bishop Eton, Liverpool?).  Dr Crompton was a business associate of James Caldwell and had various shared investments particularly in a Brewery concern.

It would appear that Peter also inherited Mapwell Hall from his father in 1770. Upon his death in 1833 Mapwell Hall passed to his son, Sir Charles Crompton.

Peter seems to have known Samuel Taylor Coleridge and William Roscoe.  Also the Strutt family.

Regarding Samuel Taylor Coleridge, Peter is mentioned on page 290 of Richard Homes book Coleridge, Darker Reflections as follows:
'By the time he reach Liverpool he was so travel-sore and flea-bitten that he postponed all thought of lecturing, and retired for several days to the country residence of his old friend Dr Peter Crompton, where he sampled another industrial product, the delicious thick ale from Crompton's 'enormous Brewery in Liverpool'.  Dr. Crompton, in turn, was soon promising to send half a hogshead for the housewarming at Berners Street.  Coleridge thought it so fine that he would never need to taste another drop of hard spirits 'in secula seculorum'.'

Dr. Crompton and his family lived in Eton Hall from 1797 to 1843. Samuel Taylor Coleridge and his family were regular visitors, and Robert Southey came in 1801.  A road near his old house is called Crompton Lane.  The site of the former Eton Hall is now called Bishop Eaton and is owned by the Roman Catholic Church.

We do have a photograph of a portrait of Mary Crompton of Eaton from Anne Marsh Caldwell's photo album.  Anne would have known Peter and Mary as they were regular visitors to the Caldwell home of Linley Wood in the early 1800s.

This letter appears to relate to Peter Crompton and James Caldwell

18th February 1793

Sir,

Mr Crompton having communicated to me a letter received from you on Saturday last, I feel myself impelled to endeavour to clear him from some of those injurious charges laid against him. This I trust from your known character, will be a sufficient apology for this intrusion.

Judge Ashursts most excellent charge had been put up on our coffee room, but that it was taken down by Mr Crompton, I may safely say, is absolutely false; which from the authority I have, I am fully justified in doing; neither have I heard of any other instance of Political outrage though I believe many injurious reports have been circulated, and very unjust aspersions cast upon him, in consequence of this very unfortunate (and as his friend I must say inconsiderate declaration of his sentiments upon the different forms of Government. And notwithstanding we may suppose a degree of impropriety looking upon him as a Magistrate; yet, if we consider him only as a private individual conversing upon any topic whatever in a mixed company, his arguments certainly ought not to be regarded further than any others of that company so as to be censured particularly on account of his Magisterial capacity. And consequently in this point of view we may prefer, the impropriety in a great measure as done away. That Mr Crompton has regarded himself in this light I have no doubt, as he has more than once declared to me, that when not absolutely acting as a Magistrate, he only considered himself as one of the company he happened to be with, and consequently looked upon himself as having the same right to argue upon any subject, and give his ideas at the moment with the same freedom as the next. Yet in no other instance can I recollect the least impropriety or any circumstance tending to show the least violence of Political disposition.

As I think it necessary for Mr Crompton’s interest that you should be fully informed of the present unhappy circumstance exactly as it happened, and as I am convinced it is Mr Crompton’s wish that I should give you this information, I will take the liberty to inclose a copy of a declaration given and signed by me to Mr Caldwell (Mr Crompton’s Attorney) and also a copy of a letter written by me to a gentleman at Bolton upon the occasion of an attorney coming here with a view to obtain affidavits upon the business. These will convey the best account, as also my impressions at the time; in as full a manner as I can give them.

I most sincerely hope your good and friendly offices, (which I have no doubt will be exerted in his favour) added to your interest with Lord Hawksbury, and a proper representation from you of the facts, may be attended with every success I wish, and that you will shortly be able to convey to Mr Crompton the [hole in letter] news, that this affair is entirely settled [hole in letter] restore happiness to his family [hole in letter] Particularly Mr Crompton [hole in letter] in such an anxious uncertain moment as just given Mr Crompton. An addition to his family [hole in letter] have felt severely, as well as Mr Crompton who notwithstanding every exertion to keep his spirits up, I am well convinced has suffered much of that uneasiness of mind naturally attending [hole in letter] uncertainty, and the reflection of the pain [hole in letter] his nearest and dearest relatives; through [hole in letter] unthinking, unfortunate moment.

I am sir, with the greatest respect

Your most [hole in letter]
