History
The estates of Glyn, Sylfaen and Ystumcegid were acquired by Sir Robert Owen of Brogyntyn and Clenennau when he married Margaret Wynn, elder daughter and heiress of Owen Wynn, in 1683. The earliest deeds in the group show that Glyn came into the possession of Ieuan ap Rees ap Ieuan ap Einion in 1499-1500. His son, John, married Gwenhwyfar, daughter of Gruffith ap Ednyfed of the Sylfaen estate. John's son, Robert Wynn, heir to both properties, married Catherine, a daughter of Eliza ap Moris of Clenennau, in 1544. The Glyn and Sylfaen estates appear to have remained as separate entities throughout the sixteenth century, since Glyn was inherited by Robert Wynn's eldest son, Moris, and Sylfaen by his second son, Ellis. After Ellis died, probably around 1620, both estates descended to Moris Wynn's son, William. The latter's eldest son, another Robert Wynn, married Catherine, daughter of Robert Owen of Ystumcegid, in 1625. The heir to all three estates was their eldest son, Owen Wynn, who married Elizabeth Mostyn of Nant in 1663. The title deeds show the acccumulation of land prior to 1682 by the successive owners of Glyn and Sylfaen in Merionethshire and in south Caernarfonshire near Dolbenmaen. In common with other landowners, the family took advantage of leases from private individuals and from the corporation of Harlech, of land which had been originally granted by the Crown. A small number of documents post-date the acquisition of Glyn by the Owen family of Brogyntyn. Very few of the Ystumcegid deeds are present, since most of the Eifionydd properties were sold and dispersed in 1911.
