Dear Polly ~
Thank you for your post. You've asked a good question.
The pedigree of the early Eure family differs depending on the source you consult. Some authors such as Dodds and Hedley have two John de Eure's in a row, some authors only one.
I've copied below my current file account of Sir John de Eure, Knt., (died 1368), of Stokesley, Yorkshire. He was the son and heir of Sir John de Eure, Knt. (died 1322), of Stokesley, Yorkshire, by his wife, Agnes. I've included my references which you can read for yourself.
Best always, Douglas Richardson, Salt Lake City, Utah

7. JOHN DE EURE, Knt., of Stokesley, Yorkshire, and Kirkley (in Ponteland), Northumberland, son and heir, born 18 October 1302 (aged 19 in 1322, 24 in 1326). He married before 1340 MARGARET _____. They had two sons, Robert and Ralph, Knt. He petitioned for livery of his lands in 1326. He did not receive livery of Kirkley (in Ponteland), Northumberland until 22 Feb. 1358. He obtained restitution of the remainder of his lands in 1360 by payment of a £400 fine. In 1364 he granted all his lands in Yorkshire to his son, Robert. In 1365 David de Strathbogie, Earl of Atholl, sued him regarding the services due from the manor of Kirkley (in Ponteland), Northumberland. SIR JOHN DE EURE died 19-25 March 1368. His widow, Margaret, left a will dated 4 April 1378, proved 27 May 1378, requesting burial in the choir of the church of Preaching Brothers, Newcastle-upon-Tyne, Northumberland.
