# The name that appears in more than one chain > Across 291 objects the recurring names in a provenance line are dealers, not collectors. And in one chain here the same surname is two different men in consecutive links. > The Study - 2026-09-10 > Canonical HTML: https://iconotheca.com/study/the-name-that-appears-in-more-than-one-chain/ ## Key points - Across 291 objects and 2,033 ownership links, only twenty-four names appear in three or more separate chains. Most of them are firms and dealers rather than private collectors, because a dealer handles many objects and a collector handles few. - A recurring name is the only node in a provenance line you can cross-check against a different object. That makes it the most useful entry in a chain for diligence, and the most dangerous one to match carelessly. - The Warwick Vase carries two unrelated men called Hamilton in consecutive links: Gavin Hamilton the excavator and dealer, and Sir William Hamilton the collector who bought from him. - The dealers who recur here do not stay inside one material. Duveen appears in six of our records across five different object types. The exception is the musical instrument trade, where W. E. Hill and Wurlitzer each appear four times and never outside instruments. ## Only twenty-four names appear in three or more chains in this archive ## A recurring name is the only cross-checkable node in a chain ## In one chain here the same surname is two different men ## The recurring dealers do not stay inside one material ## How to use a recurring name without being caught by it ## Why this archive is free to read A name in a provenance line is a string, and diligence needs a person. The recurring names are the most useful entries in any chain because they are the only ones you can test elsewhere, and for the same reason they are where a careless match does the most damage. The Warwick Vase puts a dealer and his customer side by side under one surname, and the researcher who merges them loses the sale, the price and the restoration in a single stroke. ## Questions **Why do dealers appear more often than collectors in provenance chains?** Arithmetic. A dealer handles many objects over a career and a collector handles comparatively few, so any archive of ownership over-represents the trade. In this archive of 291 objects, only twenty-four names appear in three or more separate chains, and most of them are firms. **Why does a recurring name matter for diligence?** Because it is usually the only link in a chain that can be tested against evidence held somewhere other than the object's own file. Dealers leave stockbooks, day books, photographic archives and correspondence; a private owner who appears once leaves nothing to triangulate with. **Were Gavin Hamilton and Sir William Hamilton the same person?** No. Gavin Hamilton was a Scottish painter who worked in Rome as an excavator and dealer, and he found the Warwick Vase in fragments at Hadrian's Villa in 1769. Sir William Hamilton was the British envoy at Naples, and he bought the fragments from Gavin and paid for the restoration. They occupy consecutive links in the same chain. **Do dealers specialise by material?** Not the large ones. Duveen appears in six records here across five object types and Colnaghi across three. The clear exception is the musical instrument trade, where W. E. Hill and Wurlitzer each appear four times and never outside instruments, which reflects how small and closed that market is. **Is a well-known dealer's name in a chain a good sign?** It is useful rather than reassuring. It gives you somewhere to check, which is valuable. But a firm name spanning a century covers several generations and changes of practice, so the same name at two dates is not the same evidence and should not be read as interchangeable. ## Sources - [1] Glasgow Museums Collections Online, catalogue record for the Warwick Vase, id 40016.
