This article focuses on the kinship networks of the landed gentry of Devon, Lincolnshire and Hertfordshire in the modern period. Using national census household returns, the visitors books of a Devon gentry family and correspondence the article reveals dense and meaningful kinship networks centred on the main country house but also woven into the wider familial world of the gentry. Whenever possible, the inheritance of landed estates passed through the male line. But kin networks were bilateral, founded on both birth and marriage, on relations both through the male and the female line. Kin relations provided a range of services within a culture of visiting, epistolary practice and affection, which generated close and cherished family ties.
