In 1541 Anne Bourchier 7th Baroness Bourchier (age 24) eloped with John Lyngfield.

Letters and Papers 1543. 22 Jan 1543. Cap. xliii. [o. n. 39]. Whereas lady Anne (age 26), wife of [her husband] Sir William Parre lord Parre (age 31), continued in adultery notwithstanding admonition, and, finally, two years past, left his company and has since had a child begotten in adultery, that the said child and all future children she may have shall be held bastards.

22 Jan 1543. Once [her husband] William Parr 1st Marquess Northampton (age 31) and Anne Bourchier 7th Baroness Bourchier (age 26) did live together both commenced affairs. She with John Lyngfield, prior of St. James's Church [Map], in Tanbridge, Surrey [Source. Wikipedia. However, there is no church of St James in Tandbridge?], by whom she had an illegitimate child named John Parr. He with Dorothy Braye Baroness Chandos and Knollys (age 19). To protect the interest of his subsequent children Parr (age 31) pursued legislation to disinherit her child.

A Treatise on Adultery. The first of these cases is that of Lady Parr (age 26), in the 34th Hen. VIII.; and the Act¹ states, "that for the last two years she had eloped from her husband, [her husband] William Lord Parr (age 31), and had not in that time ever returned to, nor had any carnal intercourse with him, but had been gotten with child by one of her adulterers, and been delivered of such child, which child being, as is notoriously known, begotten in adultery, and born during the espousals" between her and Lord Parr, "by the law of this realm is inheritable, and may pretend to inherit all, &c.;" and the Act therefore declares the said child to be a bastard.

Note 1. The Act, which is styled in the Lords' Journals, a Bill "to bar and make base and bastards the children which be, or shall be borne in adulteiy by the Lady Anne, wife of the Lord Parr," was read a first time on the 15th March 1543, bat it appears to have been altered by the Commons. — Lords' Journalls, I., 217. 223. 224. 230. 233. In the 6th Edw. VI., 1552, a Bill passed for annulling Lord Parr's (then Marquis of Northampton) marriage with Lady Anne Bourchier, and confirming his marriage with Elisabeth, daughter of Lord Cobham, and for the legitimation of the children that shall be had between them; but the Earl of Derby, the Bishops of Norwich and Carlisle, and Lord Stourton dissented. — Ibid, p. 409.418. The Statute of the 6 Edw. VI was, however, repealed in the 1st of Mary, 1555.
