Winterborne - a stream which flows most strongly in winter and dervies from the Old English Winterborna. The spelling of Winterborne was never constant. By local custom only Winterbourne Steepleton and Winterbourne Abbas now retrain the "u".
As can be seen below, Martinstown or Winterborne St Martin was derived from the church dedication to St Martin in the C13th.
From the tenth century, the Saxons established methods of land management and administration with land divisions known as Hundreds. These were nominally 100 hides in area. A hide was originally the amount of land that could be ploughed in a year using one plough with an eight-ox team. The area thus varied with soil quality and could vary between 60 to 180 acres. The Hundred Court, presided over by the Hundred Reeve, would usually meet monthly to consider criminal offences, minor ecclesiastical matters, private pleas and also to levy taxes.
Meetings were held at an agreed traditional site, the hundredal moot. These places were either well known by name or by physical feature and were often at the junctions of parish boundaries. Dorset had a total of 39 Hundreds, 7 met on church land, 6 on Royal Manors, 15 met at ancient monuments and the remaining 11 at geomantic sites
