In the year 1643 she obtained leave of her mother to go to Oxford, where the court then resided, and was made one of the Maids of Honour to Henrietta Maria, the Royal Consort of King Charles I. and when the Queen was forced to leave the arms of her Husband, and fly into France, by the violence of the prevailing power, this lady attended her there. At Paris she met with the marquis of Newcastle, whose loyalty had likewise produced his exile; who, admiring her person and genius, married her in the year 1645. The marquis had before heard of this lady, for he was a patron and friend of her gallant brother, lord Lucas, who commanded under him in the civil wars. He took occasion one day to ask his lordship what he could do for him, as he had his interest much at heart? to which he answered, that he was not sollicitous about his own affairs, for he knew the worst could be but suffering either death, or exile in the Royal cause, but his chief sollicitude was for his sister, on whom he could bestow no fortune, and whose beauty exposed her to danger: he represented her amiable qualities, and raised the marquis's curiosity to see her, and from that circumstance arose the marquis's affection to this lady. From Paris they went to Rotterdam, where they resided six months: from thence they returned to Antwerp, where they settled, and continued during the time of their exile, as it was the most quiet place, and where they could in the greatest peace enjoy their ruined fortune. She proved a most agreeable companion to the marquis, during the gloomy period of exile, and enlivened their recess, both by her writing and conversation, as appears by the many compliments and addresses he made her on that occasion. The lady undertook a voyage into England, in order to obtain some of the marquis's rents, to supply their pressing necessities, and pay the debts they had been there obliged to contract; and accordingly went with her brother to Goldsmith's Hall, where, it seems, the committee of sequestration sat, but could not obtain the smallest sum out of the marquis's vast inheritance, which, amounted to 20,000 l. per annum; and had it not been for the generosity and tenderness of Sir Charles Cavendish (who greatly reduced his own fortune, to support his brother in distress) they must have been exposed to extreme poverty.
