Source-derived summary

Diana Cephas was the plaintiff in a freedom suit filed in St. Louis, Missouri in 1840. She won her case after it went to trial in the Circuit Court of St. Louis County in 1843. Born into slavery in Maryland, she and her young son Josiah had been taken to the free state of Illinois in 1839, where she was hired out by her slaveholder over several months. She was then taken to Missouri, a slave state, but won her freedom with the help of freedom suit attorney Francis B. Murdoch, despite the efforts of lawyers Myron Leslie and Roswell M. Field to discredit her.

Background

Both Diana and her son Josiah had been born into slavery in the state of Maryland. Josiah was born in April 1838.

In 1839, Diana and Josiah were taken to the free state of Illinois by slaveholder Mark Delahay and his wife. Delahay settled in Naples, Illinois in July 1839 and hired Diana out to Ross Hughes for months at a time, collecting her wages.

Editorial analysis

Why this record matters

The subject matters to the general reference register because the source frames it as plaintiff in St. Louis freedom suit (1840). Its deeper value depends on whether names, dates, institutions and citations support that framing.

Evidence profile

The citation trail is more important than the brevity of the summary: it shows where individual claims can be examined in context. The source revision retrieved here is dated Feb 4, 2026. The linked authority identifier is Q111170354. None of the 0 selected statements returned an explicit reference. The first chronological checks are 1840, 1843, 1839 and 1838.

Critical limits

The absence of detail may reflect summary conventions rather than a lack of surviving documentation. 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

Use the entry as an orientation point, then follow its citations and revision history. Names, dates and institutional relationships should be checked against the original record.
