The earliest records of the family show the Darwins to have been substantial yeomen residing on the northern borders of Lincolnshire, close to Yorkshire. The name is now very unusual in England, but I believe that it is not unknown in the neighbourhood of Sheffield and in Lancashire. Down to the year 1600 we find the name spelt in a variety of ways— Derwent, Darwen, Darwynne, &c. It is possible, therefore, that the family migrated at some unknown date from Yorkshire, Cumberland, or Derbyshire, where Derwent occurs as the name of a river.

The first ancestor of whom we know was one William Darwin, who lived, about the year 1500, at Marton, near Gainsborough. His great grandson, Richard Darwyn, inherited land at Marton and elsewhere, and in his will, dated 1584, “bequeathed the sum of 3s. 4d. towards the settynge up of the Queene's Majestie's armes over the quearie (choir) doore in the parishe churche of Marton.”

The son of this Richard, named William Darwin, and described as “gentleman,” appears to have been a successful man. Whilst retaining his ancestral land at Marton, he acquired through his wife and by purchase an estate at Cleatham, in the parish of Manton, near Kirton Lindsey, and fixed his residence there. This estate remained in the family down to the year 1760.
