This article relates to a portrait of the Lancaster-based merchant William Lindow (slave-trader and slave-owner) and his wife painted by George Romney in 1772, which is exhibited at the Tate Gallery in London. It highlights the link between Lindow and transatlantic slavery and provides details about the community research project that led to the change in the description on the label of the painting. The collection of essays and illustrations in this catalogue are all in celebration of a ground-breaking exhibition which ran from March to November 2023 at the Judges' Lodgings Museum in Lancaster featuring new commissioned portraits of six Black Lancastrians by Kendal-based artist Lela Harris. Her portraits are informed by historical research including family stories, church and other public records.
