William Bolton (Royal Navy officer, died 1830)

William Bolton, Rector of Brancaster and Hollesley, whose brother Thomas was married to Nelson's sister Susannah.

[2][4] His father passed on his taste for the classics and literature, and the family spent 1786–1787 in France, where Sir William became fluent in French.

[9] He continued to serve with the fleet in the Mediterranean until October 1798, when he rejoined Nelson in Vanguard at Naples, then followed him into Foudroyant, until August 1800.

[5] After a short interval on Malta (previously the French brig Guillaume Tell), Bolton served with Nelson successively on San Josef and St George, both under Captain Thomas Hardy.

[5][22] Sir William and Dame Catherine had 5 children, of whom only 3 daughters survived to adulthood – Emma Horatia (probably named after Emma Hamilton and her daughter Horatia Nelson), Mary Anne and Ellen Catherine (who married Dr Horatio Girdlestone, grandson of Susannah Nelson).

[23] Some time later, after the death of Catherine and later her twin sister Jemima (aka Susanna), a memorial window was created in the church of St Mary's at Burnham Westgate, honouring them all.
