Source-derived summary

Mary Ann Ansell, a housemaid, was hanged at St Albans Prison, England on 19 July 1899, for poisoning her sister Caroline, who was an inmate in an asylum. Her motive was asserted to be to obtain £11.5s from a life insurance policy which she had taken out on Caroline. She sent her a small piece of cake or pastry, like a flat jam sandwich, the middle of which was very yellow and contained phosphorus poison. Her sister had been an inmate at Leavesden Asylum in Abbots Langley.

At 18 or 22 years old (reports differ), she was the youngest woman to be hanged in the UK in the 'modern era' (after the 1868 reform act, so non-public, and also by the 'long drop' method).

Before Ansell's execution, there was considerable public pressure for a reprieve, on the grounds of her sex, youth, and perceived lack of mental capacity (both of herself, and of other members of her family). The Metropolitan Asylums Board passed a resolution calling for clemency. Some newspapers, including the Daily Mail under the headline "A One-sided Investigation", asked for a reprieve. Three questions were asked in the House of Commons in relation to her case, and more than 100 MPs signed a petition that her life be spared. However, the Home Office was unwilling to reprieve a poisoner, this murder being considered a premeditated act, and poisoning an especially heinous crime under English law.

Editorial analysis

Why this record matters

The subject matters to the general reference register because the source frames it as english poisoner. Its deeper value depends on whether names, dates, institutions and citations support that framing.

Evidence profile

Named sources, stable identifiers and responsible institutions provide the strongest route from overview to verifiable evidence. The source revision retrieved here is dated Jun 20, 2026. The linked authority identifier is Q6778964. 1 of 1 selected statements include explicit references; 0 carry qualifiers and 0 use preferred rank. The first chronological checks are 1899 and 1868.

Critical limits

The absence of detail may reflect summary conventions rather than a lack of surviving documentation. The source lead contains qualifying language; that uncertainty should survive quotation, summary and reuse. Authority statements aid reconciliation but still require their own references, qualifiers and ranks to be checked.
