Anna Sophia Herbert was born in around 1610, the daughter of Philip Herbert, 4th Earl of Pembroke and Lady Susan de Vere, the youngest daughter of the Elizabethan courtier, poet, and playwright, Edward de Vere, the 17th Earl of Oxford.

[1] Their son Charles Dormer, 2nd Earl of Carnarvon was born on 25 October 1632, and baptised in St Benet's in London.

Lord Carnarvon survived her only by a few months; he was killed at the first Battle of Newbury on 20 September 1643 by a lone trooper who chanced upon him returning from a successful cavalry charge.

"[4] Their eldest son, Charles, succeeded to the Earldom on his father's death, and became Hereditary Chief Avenor and Keeper of the King's Hawks.

Lady Carnarvon's portrait and that of her eldest son, Charles, was part of the exhibition of Anthony van Dyck's works at the Grosvenor Gallery in 1887.
