Eleanor de Meriet

John de Meriet and Eleanor Beauchamp of Hatch, Somersetshire, England only had a son, Sir John Meriet born in 1345. This John de Meriet had three wives; Joan, Elizabeth de Arundel & Matilda [widow of Ralph Seymour]. His only issue was a daughter Elizabeth de Meriet born in 1386 & in 1390 promised in marriage to Uriah Seymour. Sadly Elizabeth died in 1395 and numerous Inquisition Post Mortems make it clear that there literally were no heirs from this line. If a daughter existed; she would have been a considerable heiress to the de Beauchamp Estate, but instead these properties went back to the Seymour family [descendants of Cecelia de Beauchamp], when Eleanor de Beauchamps son's line became extinct. 

The Manor of Hestercombe did have a reversion back to this family, but was actually held by another branch altogether [who also ran out of heirs]- Hestercombe came to the Warre family because of this NOT by marriage;

From Meriet of Meriet and of Hestercombe by G. W. Greenfield, pub 1883

Margery, wife of Sir Simon de Meriet, Kt. It has been already shewn that in February, 1346-7, her husband settled a life estate upon her of several manors and lands ; and that she held such an estate in the manors of Hestercombe, Combe Flory, Bradeford with the advowson of its church, Wydecombe, Elle worth, Brompton-Raufe, Wyke by Taunton, Capelond, and Assheton by Bristol; and messuages and lands in Yartecombe, Bishop's Lideyard, Kingeston, Okcombe,Legh, Plassh, Sandlane, Cerneheye by Taunton, and Lymyngton. There is presumptive evidence that she survived Sir Simon, and had married before April, 1372, Thomas de Welyngton. [Fin. Cone. Divers Counties, 47 E. III. no. 749.] See (page 152). She survived her second husband, and was living in Easter Term, 1390, when she was still holding the manors of Hestercombe and Combe Flory. [Fin. Cone.Somerset, 13 R. 11. no. 14]. This is the latest notice that is found of her. There is proof that she had died before Michaelmas, 1393, as in that Term those manors, with several other manors and lands in Somerset and Devon, were conveyed by final accord to feoffees ; as regarded the manor and advowson of the chantry of Combe Flory, to hold to the use of John Hulle and Matilda his wife, for their lives, with remainder to Nicholas Hele and Alice his wife, and the heirs of Alice ; and as regarded the manor of Hestercombe, to grant the same to Richard Warre and his heirs.
