Not sure of what you are wanting to know. Here is a derivation of the surname (take it with a grain of salt until you have traced your line back, though, as your name may have nothing to do with the Ledfords the site has found): This is an English surname. Recorded as Ledford, Ludford and Lodford, and possibly having an overlap with Lydford, a Somerset and Devonshire surname, it is locational from either of two places called Ludford in the counties of Shropshire and Lincoln, where in the latter county it is divided into Magna Ludford and Parva Ludford. In all cases the prefix is a reference to a river, and appears to originate from the Ancient British (pre Roman) word "hlude" meaning loud or perhaps fast flowing, with "forda", a shallow river crossing. Lydford in Devon is first recorded in the famous Anglo-Saxon Chronicles of the year 997 a.d. as Hyldanford, whilst Ludford in Lincoln was Ludesford in the Domesday Book of 1086, and in Shropshire as Ludesforde in the same register. The surname is much later and being locational was usually a "from" name. That is to say a surname that was given to somebody as easy identification, after they had left their original village and moved somewhere else. In this case the first known recording is believed to be that of John Lodeford of Somerset in the historical register known as "Kirbys Quest" in the year 1273, John Lydford also recorded as Ledford and Ludford, so much for early spelling, applied for a marriage licence in the city of London in the year 1450, whilst William Ludford married Vertue Roker at Canterbury Cathedral, Kent, in 1669.

If you find your ancestor is from a particular county, eg Shropshire, Lincolnshire (where there are villages called Ludford), then you can check as to whether there was a manorial family of that name. Whether you can find a connection to that line, though, is dependant on the availability of information on your family.
