Edward Plowden

This Edward would be the younger brother of Edmund Plowden, uncle to John Plowden (de facto head of family), and perhaps father to the miscreants Edward jr and Roger.

"Inquiry held at Ludlow by the oath of John Leighton, Esq, Robert Cresset, Esq, Roger Eyton, Esq, Edward Dalamar, Esq, Maurice Ludlow, Esq, Edward Leighton, William Mynton, Richard James, Thos Rowley, Thos Waryng, John Hewes, Wm Legge of Wenlock and Thos Hudson

"who say on their oath that Edward Plowden of Plowden Co. Salop, Gentleman and Roger Plowden of Plowden, Gent. on Saturday before the Feast of St Bartholomew 2 Edward IV at 4.0 p.m. at the town of Walcot in a certain lane called Mershlane of the same town, with bills[1] attacked William Walcot, and the said Edward Plowden threw a bill worth 4d which he held in his hand at the said William Walcot and so gave him a mortal wound of which he died on the Tuesday after the Feast of the Beheadiing of John the Baptist

"and they further say that Edw Plowden of Plowden, Gent, John Plowden of Plowden, Gent, Roger Corbet of Bishop's Castle, Gent, Richard Burley of Shrewsbury, Gent, Roger Betley of Betley, yeoman received and conforted the murderers. March 20th, 3rd Edw IV"

This is evidence for the existence of an EdWARD (not EdMUND) Plowden of Plowden, a John Plowden of Plowden, and a younger Edward and a Roger Plowden of Plowden. Exact relationships are guesswork.

The identity of the unfortunate William Walcot is a mystery, the more so as he is neither identified as "Gent." nor as "of Walcot". He was NOT, however, the first husband of Elizabeth Stury (who hadn't even been born yet, and her father was maybe a little boy).
