Notes for John Dawtrey
sir John Dawtrey of Moore-hall, co. Sussex. Quite a bit seems to be known about this family of Dawtreys, based close to Petworth in Sussex. Berry’s Sussex pedigrees contains his pedigree I think, but I haven’t seen that yet.
I found this in a web page on Petworth. Believe it or not, as you wish:
“For a concise but interesting outline of the ancestry of the Dawtrey family, I turn to that most charmingly written book, The Story of Fittleworth, by the Hon. Lady Maxse. It has only recently been published and may well be considered a perfect example of what a village history should be. It combines an accuracy of research that archaeologists welcome with a homely, Pleaseant style. One feels that the book will be just as much a Pleaseure to the good man in the cottage who has known his Fittleworth from infancy, as of solid worth to those who are learned in research.
Lady Maxse tells us that the ancestor of the Dawtreys came to England with the Conqueror. He was named William de Alta Ripa or de Hauterive, a name which he took from Hauterive near Alencon in France, where his forbears had held land. A younger son of William, named Robert, came to Sussex in attendance upon Queen Adeliza, the wife of Henry I. This Queen married secondly William de Alblni, Earl of Arundel, and in 1139 she and her husband granted lands in Sussex to Robert de Alta Ripa. Queen Adeliza also granted lands in the Honour of Petworth to her half brother, Joscelin de Louvaln, son of the Duke of Brabant. He had married the great north country heiress, Agnes de Perci, and had taken her name. It was in this way that the Percy family became established at Petworth. It is said that Robert de Alta Ripa married the sister of Agnes Perci.
Berry gives a pedigree of the later members of the family whose original name of foreign origin became anglicised into Dawtrey. The Chapel of St. Thomas, in Petworth Church, was owned by this family of great landowners and it still contains the beautiful sixteenth-century tomb of Sir John Dawtrey and his second wife, whose maiden name was Johanna Scardeville.”
A copy of this book is in the West Sussex Archives.
