Sir Thomas Isham, 3rd Baronet

Sir Thomas Isham, 3rd Baronet of Lamport (15 March 1656/57 – 26 July 1681) is known for a diary he wrote from 1671 to 1673 of his observations as a teenage member of the English aristocracy.

[2][3] Returning to Lamport, Sir Thomas contracted to marry Mary van de Bempde, the daughter of a Dutch merchant, but he died of smallpox in London on 26 July 1681 before his marriage could take place.

[4][5] He was buried several days later on 9 August in Lamport, and succeeded in the baronetcy by his younger brother Sir Justinian Isham, who became the 4th baronet.

It is made up largely of one-sentence entries, with occasional longer anecdotes of local newsworthy events, as relayed to the boy by visitors.

[7] His diary first became widely available in 1875 when it was first published, but the most readily available edition is a 1971 publication of a translation by Norman Marlow with annotations by the 12th baronet Sir Gyles Isham.
