Edward Somerset, 4th Earl of Worcester (bef. 1568 - 3 March 1628) was the only child to the 3rd Earl of Worcester and Christian North . On February 21 1589, he succeeded his father as Earl of Worcester, and in 1593 he was made a Knight of the Garter. He was an important advisor to King James I, serving as Lord Privy Seal.

He married Elizabeth Hastings and had four children:

• Henry Somerset, 5th Earl of Worcester, his heir and successor, who was later created the 1st Marquess of Worcester;
• Thomas Somerset, 1st Viscount Somerset (Peerage of Ireland), who was born in 1579, died in 1649; he was created Viscount Somerset on December 8 1626; in 1616 he married Helen Barry - her third marriage -, with whom he had one daughter:
  • Elizabeth Somerset, who might have died young, but that is unsure;
• Lady Catherine or Katherine Somerset, who died on November 6 1654 and, before January 14 1607, married Thomas Windsor, 6th Baron Windsor , with whom she had no issue; and
• Lady Blanche Somerset, who died October 28 1649, and married Thomas Arundell, 2nd Baron Arundell , with whom she had one son and two daughters, his only children; the settlement for this marriage was on May 11th, 1607.

Some souces also consider Lady Frances Somerset, wife of William Morgan, 1st Baronet Of Llantarnam to be his daughter.
