Chance Brothers

Draft source-backed Chance Brothers lighthouse, lightship, lens, and apparatus records grouped by source family. Chance Heritage Trust imports stay separate from curated web-researched rows that require at least two reviewed sources; web research rows show an evidence grade and score when scored.

Related Chance Brothers research has continued since the 2022 collaboration with Chance Heritage Trust. See the Chance Brothers Heritage collection, and BBC News coverage of Chance Glassworks and the volunteer lighthouse mapping project: The glass pioneers who helped illuminate the globe.

Unpublished findings are generated from the review queue and are shown here as counts only. They do not appear as public asset rows until promoted through source review.

Detailed OSM map loads by default; use this control to retry or refresh. LUX Light Archive stores only the source-backed GeoJSON overlay. Marker clustering groups nearby points at wider zoom levels; zoom in or click a cluster to expand.

Detailed mode uses live standard tiles from OpenStreetMap contributors through vendored Leaflet; Chance Brothers points come from linked source-evidence cards and source-family labels. No map tiles are bundled or stored for offline use.
