Two listings for Thornbury family history fair give different closing times

The Bristol & Avon Family History Society's Family and Local History Fair is advertised in two listings that do not agree on when the event ends. One listing says Saturday 17 April 2027, 10am to 3pm, at Turnberries Community Centre, Thornbury; the other gives the same date and venue but 10am to 4pm [1][2]. Both listings say entry is free and include family and local history groups, archive offices, national organisations and commercial exhibitors, plus a free family history talk in the afternoon [1][2]. The society has separately advertised a Bath Group Zoom talk on Monday 28 September on prison, criminal and legal court records [3].
