Graig Shipping was incorporated on 15 July 1919 and remained stock-exchange listed until the Williams family acquired the minority holdings in 1993, retaining plc status. The source report identifies Idwal Williams & Co. as full owner and records ventures with Clipper interests, a Confidence Group affiliation, and subsidiaries including Graig Ship Management, Graig (Bermuda), Garth Resources and Danwel. Sektau Shipping was formed in Hong Kong in 1981; a separate later note questions whether Graig still operated under its own name.
