Same Day [Monday] died, at Tewin Water, in Hertfordshire, aged 98, the Right Hon. the Lady Dowager Cathcart.

Derby Mercury, 6 August 1789

Last Friday night a gipsey was delivered of two male children in a wood near Tewin Water, Hertfordshire, which were nearly starved to death from cold, and the want of clothes to cover them. The circumstances being made known early in the morning to Mr. Henry Cowper, who resides near that part of the country, he immediately ordered the unfortunate woman and her children to be supplied with every article that could make them comfortable.

Henry Cowper, esq., of Tewin Water, endowed a chaplaincy at Hertford Infirmary.

Hampshire Advertiser, 18 June, 1836

Henry Cowper, Esq. of Tewin Water, near this town, has made a most munificent donation of £500 to the Society for the Promotion of Christian Knowledge. Nothing can exceed the munificence of this worthy individual towards the poor in his neighbourhood, and he is anxious at all times to promote objects for their temporal and spiritual benefit.

Hertford Mercury, 6 December 1836

EXTRAORDINARY OCCURRENCE - On Friday week as a person was walking in the beautiful grounds of Henry Cowper, Esq., of Tewin Water, he chances to look into one of the highly ornamental vases (which stand in front of the drawing-room window, for the purpose of containing flowers) when to his great astonishment he perceived inside of it the nest of a small bird, with three eggs in it, which seemed quite fresh, though very late in the year. It is, indeed, one of the most singular instances of the kind which has been remembered in that part of the country for some years, as the aperture which admitted the bird is not more than three-quarters of an inch in Breadth. - Herts County Press

TEWIN WATER SALE: - Mr Jackson has concluded his arduous tasks of seven days' labour, in the disposal of the property entrusted to him by the Executors of the late revered and respected old English gentleman, Mr. Henry Cowper. We are assured that the amount received was much beyond the expectations of the parties most interested and this arose, as we think, from various causes: much and deep interest inthe sale was felt bu the public in all directions; competition was evident in many cases, induced by a desire to posses some relicc of one so justly beloved for his princely munificence to the needy and suffering poor. The admirable arrangements made also by the auctioneer greatly contributed to the success of the sale. The furniture sold remarkably well; the old rum made 12s. 6d. a bottle; the plate excited a sporting competition; the portrait of "The Witch" was sold for 18 guineas; and the flock of sheep was sold for 1s per pound.

The Truly Great Man: one who uses his riches for God's glory.

A Sermon preached in the parish church of Tewin, on the Sunday after the funeral of HENRY COWPER, Esq. of Tewin Water

by the Rev. John  Steel, B.A.

Curate of Tewin.

Printed at the Request of the Parishioners, Hertford: Cobb, 1840

The Hertford Mercury printed a description, including an extract which is mainly flowery words saying very little of import except for:

... To his fostering care the schools of Tewin, Digswell, and Hertingfordbury, owe their maintenance and efficiency. To his lordly munificence that admirable institution - the Hertford Infirmary - is in great measure indebted for its erection and support. He provided entirely at his own cost and income for a resident medical attendant: and the chaplainship also of that institution was exclusively his own endowment. ...

Hertford Mercury 2 January, 1841
