ELSTREE, (Hertfordshire) stands on an eminence, 1 m. from Stanmore, and in the road from Watford to High-Barnet, and bet. Totteridge and Aldenham. 'Tis also called Eaglestree, Illstree and Idlestree. The Watling-street of the Romans, which passed here, became in length of time so ruinous, that it was therefore called Ellstree, or Illstreet. It bel. heretofore to St. Alban's-abbey; but at the Diss. it was granted to Anth. Denny, Esq; one of whose descendants sold Parkbury manor (so called from the abbot's park here) in the R. of Ja. I. to Rob. Briscoe of Aldenham, who sold a part of the manor to Sir Baptist Hicks, and conveyed the other to his nephew Edw. Briscoe, whose son sold it to Edw. Beauchamp; upon whose death it came to his son, the present possessor. The E. of Salisbury has a manor here, and part of Parkbury is in the possession of the widow of Joshua Lomax, Esq;.
