Our Cousins in Ohio is an account of a year in the life of a Quaker immigrant family in Ohio in the 1840s, written by Mary Botham Howitt. It is based on letters from her sister Emma Botham Alderson (1806–1847), who left England in 1842 with her husband, Harrison Alderson (1800–1871), and three children, William Charles (1837–1914), Agnes (1839–1925), and Anna Mary (1841–1934). In the Preface, Howitt describes Our Cousins in Ohio as a "companion volume" to The Children's Year (1847), which had documented, in a similar way, a year in the life of her own two youngest children, Margaret and Charlton Herbert.
