The registers distinguish G. Ch. Lemos and Lemos S.A. at Chios, P.A. Lemos & Associates in London, John Lemos & Sons in Piraeus, and the London concerns G. Lemos Brothers and Christos Lemos & Sons. These entries are retained as distinct identities rather than combined into a single company.
Keep the explicit scope label independent; no alias or company identity is inferred.
