Some months after the Duke’s death, his widow gave birth to a son, named Francis after his grandfather, who provided for him in a fortune of 1,000_l._ a-year. When he grew up, however, Francis shared with his brother the misfortune that overshadowed the family, from the unexpected second marriage of their mother to Randolph Macdonald, first Earl and afterwards Marquis of Antrim. It is painful to find the widowed Duchess separated from her children, having become a Roman Catholic; and having incurred in this, and on account of the conduct of her husband in Ireland, under Sir Thomas Wentworth, the King’s displeasure. Charles so greatly disapproved of her marriage, that he refused, for several years, to see her, and, when reconciled, took away her children lest they should be imbued with her religious opinions. The young Duke and his brother Francis were educated, unhappily for themselves, with the Princes, Charles II. and his brothers; and Lady Mary was received in the house of the Earl of Pembroke, her father-in-law. Such are the changes and chances of life, that in 1639 we find Katharine, (still signing herself “Katharine Buckingham”) interceding with Strafford for her husband, Lord Antrim. “Any misfortune,” she writes, “to my lord must be mine.”[137] Footnote 137: "My Lord,--I was in hope, till very lately, that all your displeasure taken against my lord had been past; but, in letters sent me out of England, I was assuredly informed your lordship was much disgusted still with him, which news hath very much troubled me. I cannot be satisfied without sending these expressly to you. And I beseech you that, whatever you do conceive, you will deal clearly with me, and let me know it, and withal direct me how I may remove it. I must necessarily be included in your lordship’s anger to him, for any misfortune to my lord must be mine, and it will prove a great misfortune to me to live under your frowns. Out of your goodness you will not, I hope, make me a sufferer, who have never deserved from you but as “Your Lordship’s “KATHARINE BUCKINGHAM. “Dunbere, this 2nd of September, 1639.”[138] Footnote 138: Strafford Letters, vol. ii., p. 386. For him she had sacrificed indeed the favour of the King, and the guardianship of her children.
