Edmund FitzAlan

Sir Edmund FitzAlan (c. 1327/1329–1382), also called Edmund de Arundel, was the only son of Richard FitzAlan, Earl of Arundel, and Isabel le Despenser, and a great-great-grandson of Edward I. He was heir to the earldom until his parents' marriage was annulled in 1344 and he was declared illegitimate.

Knighted in 1352, he served as a soldier and envoy: he fought in France in 1359–1360, carried Pope Urban V's report to Edward III in 1368, and fought under the Black Prince at Pontvallain in 1369–1370.

After his father died in 1376 he quarrelled with his half-brother Richard over the earldom, was held in the Tower of London in 1377, and never won it back. He sailed for Gascony in 1381 and was dead by February 1382; his three daughters by Sybil Montagu later sued their half-uncle the Earl of Arundel and failed.
