Katherine Clifton, 2nd Baroness Clifton

Katherine Clifton, 2nd Baroness Clifton (c. 1592 – buried 17 September 1637), was an English-born Scottish peer (later known as the Countess of March, then Duchess of Lennox and then Countess of Abercorn).

Baroness Clifton was the only surviving child of The 1st Baron Clifton and his wife, Katherine, and inherited her father's title when he committed suicide in 1618. In 1609, she had married Lord Esmé Stewart, a younger son of The 1st Duke of Lennox. In 1619, he was created Earl of March and later inherited the Dukedom of Lennox when his brother, the 2nd Duke, died without legitimate heirs in 1624. The duke and duchess had eleven children:

• Lady Elizabeth (1610–1674), married the 22nd Earl of Arundel.
• James, later 4th Duke of Lennox (1612–1655)
• Lady Anne Stewart (1614–1646), married Archibald Douglas, Earl of Angus.
• Henry, 8th Seigneur d'Aubigny (1616–1632)
• Francis (1616–1617)
• Lady Frances (1617–1694), married the 2nd Earl of Portland.
• Margaret (1618–1618), died young.
• George, 9th Seigneur d'Aubigny (1618–1642)
• Ludovic, 10th Seigneur d'Aubigny (1619–1665)
• Lord John (1621–1644)
• Lord Bernard (1623–1645)

Her husband died later that year, in 1624, and Katherine then married The 2nd Earl of Abercorn, c. 1632. They had three children:

• James, Lord Paisley (c. 1635 – bef. 1670)
• Col. William Hamilton (d. bef. 1670)
• George, later 3rd Earl of Abercorn (c. 1636 – bef. 1683)

On her own death in 1637, her title passed to her eldest son, The 4th Duke of Lennox.
