Source-derived summary

Amy Duggan "Sister" Archer-Gilligan (October 31, 1873 – April 23, 1962) was a nursing home proprietor and serial killer from Windsor, Connecticut. She murdered at least five people by poisoning them. One of her victims was her second husband, Michael Gilligan; the others were residents of her nursing home.

It is possible that Archer-Gilligan was involved in more deaths. The authorities counted 48 deaths in her nursing home, the "Archer Home for the Elderly and Infirm."

The case attracted wide publicity at the time and has been cited as an inspiration for the play Arsenic and Old Lace.

Childhood and marriages

Amy E. Duggan was born on October 31, 1873, to James Duggan and Mary Kennedy in Milton, Connecticut, the eighth of ten children. She attended the Milton School and the New Britain Normal School in 1890.

Amy Duggan married James Archer in 1897. A daughter, Mary J. Archer, was born in December 1897. The Archers first became caretakers in 1901, hired to care for John Seymour, an elderly widower.

Editorial analysis

Why this record matters

The phrase “serial killer” supplies a clear boundary for inquiry. It also exposes the unanswered questions: who defined that boundary, when it became stable and which sources sit outside it.

Evidence profile

Vocabulary and entity names are the principal evidence signals here, because they determine the precision of every later search. The source revision retrieved here is dated Jul 8, 2026. The linked authority identifier is Q421609. The first chronological checks are 1873, 1962, 1890 and 1897.

Critical limits

Overview language is designed for orientation and should not be treated as a substitute for the evidence cited beneath it. The lead is largely declarative, so disagreement and counter-evidence require a deliberate search beyond the opening account. Authority statements aid reconciliation but still require their own references, qualifiers and ranks to be checked.

How to read it
