It’s difficult to know where to place Sarah on the Lanyon tree. We have very little information about her. This is my attempt to fit her in.

The De Banco Roll – Trinity 4 Henry V (1416)
Tredyn Lands – The plaintiffs – John Nanfan and Robert Vyhan sued their cousin Benedict Molure all three being sons and heirs of Geta, Isabella and Joan Penneck, granddaughters of David Lanyein.
So from this document we know that Geta, Isabella and Joan Penneck were graddaughters of Sarah Lynyen and great grand daughters to her father David.
Charter of 1284
“John de Leynen to David his son and William de Trenyer chaplain and to the heirs of the body of the said David by Marina his wife. Charter with warranty of all his lands and messuages in the towns of Lennyen, Resik, Bossewolonwyan, Polgon, Hendrenythyn, Boswolnel and Trengwenton, with two mills corn and fulling in Lenyen, and the rent, service and homage of Ralph de Pendyn and his heirs for land there, and of Michael Penneck, Sarah his wife and their heirs for land in Trethyn by Treudreuen.”
Dated Lanyen Friday before St Peter’s Chains 12 Edward I
From this document we know that Michael Penneck was the husband of Sarah and held lands at Trethyn. David was the son of John de Leynen and was married to Marina and held lands at Lanyon and Rissick that were still held in the 17th century. From the De Banco Roll we know that David had a son-in-law called Penneck so it seems logical to place Sarah as his daughter.

There is also a David De Linien who was a witness to a Charter of Glasney College dated 10th October 1267. Advowson of St Sithney Church by Roger de Skyburriow.
But there is also a mention of a David de Lynyen on the Lay Subsidy Roll of Madron 1 Edward III (1327) he was assessed at 4 shillings? Is he David de Lennyen or his son David de Kylminawis or another David altogether?
Therein lies the problem with researching families at this time you don’t know for sure who the documents refer to.
