Regarding Olivers, known also as Hyde Hall, East End or Southall, there is this:
In 1490 this estate belonged to Matilda Exton in her own right, and she together with John Barbour, her son by a former marriage, conveyed it to Richard Fyfehid alias Lowe and other trustees, (fn. 118) who granted it in 1492 to Leonard Hyde of Throcking and others. (fn. 119) These appear to have been acting only as trustees. In 1506 they transferred the 'manor' to Sir Robert Drury, kt., and others, who in turn conveyed to Thomas Sandon. (fn. 120)
