Jane Thweng of Cornborough

✓ Jane, da. of John FitzEdmond Thweng of Cornborough near Sheriff Hutton (d. 1369, IPM), and eventual heiress of her brother Marmaduke Thweng of Cornborough (d. 1426); wife of John de Westhorpe of Brompton (d. 1430); taxed with him 1381. Through her the Westropps obtained Cornborough (a third of it recovered by her great-grandson Richard in 1495 on proof of this descent). THE THWENG DOOR: the Thwengs of Cornborough were a branch of the Thwengs of Kilton (Marmaduke de Thweng, 1st Lord Thweng, d. 1323); John FitzEdmond's place in that family is to be established - CP XII/2 'Thweng' (not online), the Yorkshire Visitations and VCH North Riding (Sheriff Hutton) are the sources. Her father not yet wired.
