Danvers is a toponym, derived from the French town of Alvers. The name went from d'Alvereau to d'Anuers to d'Anvers. During the late 13th-early 14th century, the Anglicized Danvers came into use.
Roland d'Alvereau served with William the Conqueror. His son Ranulph d'Anuers was awarded the manors of Marlow, Dorney and Huckham by Lord Crispin of Wallingford.
From their arrival in England, the family was active in government and politics of their adopted country. They were rewarded with estates and privileged marriages. Samuel Danvers was created Baronet Danvers of Culworth on March 21, 1642.
There are two principle Danvers lines in ancient England. One branch of the family settled near Culworth in Northamptonshire and the other settled near Banbury, Oxfordshire. This second branch resided at Colthorpe Manor. The similarity in estate names has caused much confusion when tracing the families.
