Stilwell & Sons (before 1774-1923), established in London, was a past constituent of NatWest.
This naval agency was established by John Gathorne (born 1726) in the City of London at Crutched Friars, next to the Navy Office, sometime before 1774. Gathorne was a merchant trading with Madeira, Azores and South America. He later took his friend James Sykes into partnership, and after Gathorne's death in 1774 Sykes continued to trade alone.
The firm moved to 22 Arundel Street, Strand, in 1792 when the Navy Office was relocated to Somerset House. Subsequently Sykes took his son James into the partnership, which became known as Sykes & Son.
In 1813 Thomas Stilwell, a kinsman, was taken into partnership. Sykes senior and junior both died in 1816, leaving Thomas Stilwell as sole partner. Stilwell was eventually joined by his sons and grandsons and the firm was later known as Stilwell & Sons. The firm moved to Great George Street in 1884, and later to 42 Pall Mall.
In 1923, when the partners were Geoffrey Holt Stilwell, John Bernard Lethbridge Stilwell and William Byron Stilwell and its balance sheet totalled £164,620, the business was acquired by Westminster Bank.
