The Anson Baronetcy, of Birch Hall in the County of Lancaster, is a title in the Baronetage of the United Kingdom held by a branch of the Anson family. It was created on 30 September 1831 for William Anson. He was the third son of George Anson; his elder brothers were Thomas Anson, 1st Viscount Anson and General Sir George Anson. Sir William was the uncle of Thomas Anson, 1st Earl of Lichfield and Major-General George Anson and the great-nephew of George Anson, 1st Baron Anson (see Earl of Lichfield, 1831 creation for more information on the Anson family). His grandson, the third Baronet, was a lawyer and Liberal Unionist politician. He never married and was succeeded by his nephew, the fourth Baronet. He was the only son of Frederick Arthur Anson, third son of the second Baronet. The fourth baronet drowned in the Thames in July 1914, aged only twenty-five. He had not married and on his death the title passed to his first cousin, the fifth Baronet, the eldest son of Rear-Admiral Algernon Horatio Anson (1854–1913), fourth and youngest son of the second Baronet. He was killed in action in the First World War. He was unmarried and was succeeded by his younger brother, the sixth Baronet. As of 2007 the title is held by the latter's son, the seventh Baronet, who succeeded in 1951. He is a retired Rear-Admiral in the Royal Navy.
