Shortly after the death of her father, Susan married
Philip Herbert at the royal court on 27 December 1604.
Prince Henry and the
Duke of Holstein escorted her to the chapel. The Queen followed and King James gave the bride away. The Venetian ambassador
Nicolò Molin wrote that there was a banquet, but dancing afterwards was cancelled because of the crowds. After supper a
masque Juno and Hymenaeus was performed in the hall at
Whitehall Palace by courtiers.
Dudley Carleton was impressed by the masquers except Thomas Germain, who "had lead in his heels and sometimes forgot what he was a-doing". According to Carleton, there some disorder and pilfering at the wedding masque, jewels and gold chains were lost, and some skirts. A few days later Lady Herbert appeared in the
Masque of Blackness. Philip Herbert was an English
courtier and politician active during the reigns of
James I and
Charles I; he was the son of
Mary Sidney. A year after their marriage King James created him Baron Herbert of Shurland and 1st Earl of Montgomery; in 1630, after Susan's death, he would succeed his older brother as 4th Earl of Pembroke. Philip Herbert and his older brother
William Herbert, 3rd Earl of Pembroke were the "incomparable pair of brethren" to whom the
First Folio of
Shakespeare's collected works was dedicated in 1623. At court, she played the part of "Flora" in
The Vision of the Twelve Goddesses on 8 January 1604, "Malacia" in
The Masque of Blackness on 5 January 1605, and on 5 June 1610 she danced at
Whitehall Palace as the "Nymph of Severn" in the masque ''
Tethys' Festival''. ==Children==
