Mare of Easttown Codexery — Data & Quality

We publish our audit record because accuracy claims should be checkable. Every entry on this site runs through an automated fact-audit pipeline (accuracy audit → source-grounded repair → visual QA); this page is generated from that pipeline's own report, not written by hand.

This is a fiction/fan codex: entries describe an in-universe canon. Our audits check canon and internal consistency — external fact-checking does not apply the way it does on real-subject codexes.

Recent findings (audit lane, verbatim)

Sean McMenamin — The entry states that Erin McMenamin's disappearance and subsequent murder form the core mystery, but in canon, Erin is found dead early in the first episode; there is no 'disappearance' period before her body is discovered.

Kevin Sheehan — The claim that Kevin scored the winning basket for Easttown's first state championship 25 years prior is incorrect; the championship was won 25 years before the series, but Kevin was a teenager at that time, making the timeline inconsistent with his age (he wo

Kevin Sheehan — Mare recalls Kevin's voice from a documentary as she passes out after shooting Wayne Potts in the finale 'Sacrament', not in the episode 'Illusions'.

Grief and Loss — The character is named Brandon Ashbrook, not Brandon Ashland.

Grief and Loss — The character is named John Ross, not John McVey; Kenny McVey is Erin's father.

Hear the Silence — The episode 'Hear the Silence' is the fifth episode, not the sixth.

Hear the Silence — The main character's full first name is Marianne, not Catherine.

Frank's Heart Attack Reveal — Frank Sheehan does not die from a heart attack while driving; he dies at home.

Mare Sheehan House — The 'DID YOU KNOW' section states that Mare scored the winning basket in a high school basketball game that won Easttown its first state championship 25 years prior to the series, but the series does not state it was the first state championship for Easttown.

Easttown Police Station — The entry states that Detective Colin Zabel was brought in from 'the county,' but in the series, Zabel is a county detective from the Delaware County District Attorney's Office, not simply 'from the county' in a vague sense—this is minor but imprecise.
