House Wanted, containing ten or twelve rooms, with a good-sized yard situate within a half a mile of the centre of Regent-stree. Particulars to be sent (post paid) to Mr. Mark Moore, 2. Queen-street-place, Southwark-bridge, City.
1839 Mark Moore published the following advertisement in The Morning Post, London, on September 13: 
Mill-Hill.--A family cottage to be let, with immediate possession, consisting of three parlours, drawing room, five bedfooms, two attics, kitchen, scullery, and large garden. For particulars apply to Mr. Mark Moore, 2. Queen-street-place, Southwark Bridge, City; to Messrs. Paxon, Hampstead; or to view and terms, to Mr. Wood, Builder, Mill-hill, Hendon, Middleses. Mr. Moore, as Receiver and manager, has leisure to undertake another estate, in London or its vicinity, should any Nobleman or Gentleman be in want of such assistance. Terms moderate, references most respectable.
1841 Mark Moore (age 61), private boarding house keeper, Elizabeth Moore (age 55) and Charlotte Delahoy (age 28) lived at 6 Queen Street Place, District 15, St Martin Vintry, Middlesex. 
1849 Mark Moore died on August 13 in London. An obituary in The Baptist Magazine states, 
Mr. Mark Moore.
Died, August 13th, Mr. Mark Moore of Queen Street Place, Southwark Bridge, many years a deacon of the church meeting in New Park Street. Mr. Moore's health had been failing for some months, but his removal was eventually occasioned by a sudden attack of the prevailing epidemic.
1849 Elizabeth Moore published the following notice in The Newcastle Courant on September 7: 
Mrs Eliz. Moore, Widow of the late mark Moore, 5, Queen Street Place, Southwark Bridge, City, London, Begs to inform her Friends that she continues the Boarding Establishment as before, and takes thia Opportunity of thanking her Friends for their kind Support during a Residence of 15 Years in the above Place.
1850 An obituary for Mark Moore was published in Nottingham. 
We have the gratification of copying from the Boston (U.S.), “Christian Watchman and Reflector” (written by the Rev. Baron Stow), the following biography of Mr. Mark Moore, brother of the late Mr. B. Moore, of Hockley Mill, in this town, and uncle to Mr. S. W. Moore, the present proprietor, which will be read, no doubt, with interest, particularly by those who had the pleasure of his acquaintance. – “Many Americans remember with pleasure Mr. Mark Moore, of Queen-street-place, near Southwark Bridge, London. In his boarding-house, superintended by his excellent lady, they have found a quiet Christian home, and there formed acquaintance, not only with a well-ordered family, but also with pious disciples from various parts of the British Isles, and from other countries in both hemispheres. Memory will be quickened, and tender recollections awakened, as they learn that this man of God has recently fallen a victim of that mysterious disease, which has this year (1849) hurried so many of the excellent of the earth to the tomb. Mr. Moore was a member of the New Park-street Baptist Church, whose place of residence is near his late residence, on the opposite side of the Thames. This church was formerly located in Carter-lane, and for more than one hundred years enjoyed the ministry of Drs. Gill and John Rippon, whose portraits hang in the vestry, and whose bodies rest not far from each other in Bunhill-fields Cemetery. Of this church, Mr. Moore was also a deacon who used the office well. For several years he had been mostly free from secular cares, and devoted himself with great industry to works of Christian usefulness; and in various departments, as in the New Park-street congregation, the Religious Freedom Society, and the Christian Instruction Society, he was eminently useful. In the great day, when every man’s work shall be known, few laymen will have more than he to rise up and call them blessed. He was distinguished for dignity, urbanity, and general Christian bearing. Liberal in his feeling, he loved all the followers of Christ, whatever their nation, colour, or creed. His charity was comprehensive. He uttered the shibboleth of no party, and required none of others as a passport to his friendship. At his table, the writer of this has met the descendants of each of the sons of Noah, and all were equally welcomed, served, and honoured. But he has been called to his everlasting home. That fine, manly form, which ever commanded admiration, has yielded to the blast of pestilence. That still manlier soul, noble by nature, and perfected by grace, has closed its mission, and entered the better country with which it had long held intimate communion. Happy, indeed, would it be, if every family had such a head, every church such a deacon, every district such a Christian labourer.”
1851 Elizabeth Moore (age 64), boarding housekeeper, lived at 5 Queen Street Place, District 16, St Martin Vintry, Middlesex with Lydia Moore (age 24), daughter Charlotte Jennings (age 36), and son-in-law Angus Jennings (age 34), merchant. Elizabeth was born in Deptford, Kent. Lydia and Charlotte were born in Greenwich, Kent, and Angus was born in Herts. 
1861 At the time of the England census, Elizabeth Moore (age 76), boarding house keeper, and her daughter Elizabeth Cushman (age 50), Baptist minister's wife, were living at 11 Queen Square in the Finsbury bureau of London in the parish St. George the Martyr. The elder Elizabeth was born in Deptford, Kent, and her daughter in Greenwich, Kent. Also in the household were Elizabeth Moore's son-in-law, Thomas A. Burr (age 34, born in Chatham), her daughter Lydia Burr (age 34, born in Greenwich), wife of Thomas, granddaughter Elizabeth Burr (age 6, born in Islington, Middlesex), grandsons Alfred Burr (age 5) and Thomas (age 1), both born in Holborn, Middlesex, sister Martha Omer (age 57, born in Deptford, Kent), teacher in a Ladies School, four servants, and a boarder. 
1867 A family Bible record of daughter Elizabeth states, "Elizabeth Moore (my mother) died August 3rd, 1867 aged 84." 
Edith Miles Todd wrote in her genealogy notes that the Delahoy family was of Huguenot origin. 
The Delahoys (De La Hayes) of Huguenot origin. The family notable in France and when they first emmigrated to England, but lost all of their possessions. Gilbert Jennings says a lot went to worthless relatives named Merrick. [James Olivant Delahoy's sister married a Merrick.] ... [James] was cast off by family for being a Calvinist and Baptist. Was of a splendid character however. Signs himself Jr. in 1808 in a letter to his sister-in-law Charlotte Omer (which I possess). His wife married again Mark Moore and had 2 children Mary (d.y.) and Lydia (Burr). I have seen his will which Gilbert Jennings owns and have a copy of it. In my grandmother's Bible which I have is a copy of births and deaths from the Bible of Elizabeth Omer Delahoy Moore. She says that James O. was 29 years 4 months when he died. Also says died Mar. 5, 1812.
The Exeter Working Papers in British Book Trade History [http://www.devon.gov.uk/library/locstudy/bookhist/] provides the following information about James Delahoy but has merged information for the James and his son James Olivant as it is the printing operation of James Olivant Delahoy that was bequeathed to and continued by his wife Elizabeth. The senior James became an auctioneer after his career as a printer.
