Recorded as Kingsbury, Kingbury, Kingaby and Kingerby, this is an English surname. It is locational from a place in Warwckshire called Kingsbury, or from Kingsbury, a now 'lost' medieval village near the town of Aylesbury in Buckinghamshire, or Kingsbury in Middlesex, now part of Greater London, or finally Kingerby, a village in the county of Lincolnshire. In all cases the place name and hence the surname does mean 'The kings fortress,' from the pre 7th century Olde English 'cyne-burg,' and is a reminder of ancient times before the Norman Invasion of 1066. The very first surviving place name recording is probably that of the year 1045 a.d. and this refers to the original Middlesex village then called 'Kynges byrig'. The surname is medieval, and the first known recording is probably that of Adam de Kingesbire, in Lincolnshire, in the Hundred Rolls of 1273. He is believed to have been the Lord of the Manor of Kingerby. Other recordings include Phillip de Kingsberrie of the county of Dorset also in 1273, and five centuries later the recordings of Mary Kingsbury who married John Gibbs at St George's Chapel, Mayfair, Westminster, in 1791, and James Kingaby who married Ann Andrews at the same church in 1794.
