Gwladus, Gwenllian's cousin, in the convent at Six Hills near Market Rasen, Lincolnshire:
It is proposed to place information about Gwladus in a central site in the village. People in the area talk of "the Grave of the Welsh Princess".

The Lost Children - were they taken from Wales to Lincolnshire by sea?
The Society is currently investigating the history.

Proposed local group:
It has been suggested that a local Gwenllian group could be set up, based on Sempringham, for members living in neighbouring parts of England. Please let the Webmaster know if you'd be interested in joining this group.



2018: The slate memorial on the summit of Snowdon was stolen and destroyed by vandals in the spring of 2018. Gary Eccleston, a slate craftsman form Prestatyn offered to design and make a new slate plaque to replace the original. He offered to make this and to install it on site free of charge. This was done on September 15th, 2018.

2019: At the end of the summer, severe damage was caused to the slate plaque on the Gwenllian memorial in Sempringham making it necessary for it to be replaced. The Society commissioned Gary Eccleston to make a similar plaque to the original which was designed and crafted by Ieuan Rees. Gary Eccleston accepted, and it is hoped that the new slate plaque will be in position early in 2020.

Beaumaris News
Recently there has been discussion regarding the identity of the lady depicted on the lid of the stone coffin in the porch of St Mary’s and St Nicholas Church in Beaumaris. This followed a presentation given by historian Dr Madeleine Grey to the Society’s AGM in Worcester Cathedral in 2016 where she questioned whether the depiction was that of Joan, the wife of Llywelyn the Great, which has long been accepted. She believes that the depiction represents a lady of the late 13th century rather than the middle of the century (Joan died in 1237) and suggested that it might be Eleanor de Montfort (died 1282) the mother of Princess Gwenllian. The Society commissioned an information plaque from Janet Elson Griffiths to be placed in the Church porch above the coffin and it is hoped that this will be placed in situ shortly. Also, the society has published a bookmark and an information card to accompany this development. These can be seen in the Goods for Sale section.

The long awaited volume about some of the fateful events of 1282, based on a number of booklets written by the late Anthony Edwards, has been printed and is on sale for £8.50 (+ £1.50 p&p - £2 p&p for two books). The English language book is the work of Mrs Janet Elson, whilst the Welsh version 'Wyneb yn Wyneb â Brad', translated by the Society's former chairman, is also available at the same price.

On Wednesday 29 January, 2014, following a decision taken in the recent Meeting of the Executive Committee, the former chairman presented a framed picture of the Society's plaque on the summit of Snowdon to Mike Robertshaw, Senior Engineering Manager of the Snowdon Mountain Railway Company, together with a pack of information leaflets about the plaque, which will be given to every passenger using the train to reach the summit.

In the picture is the former chairman presenting the picture to Mike Robertshaw in his Llanberis office.

The Six Hills Yews
Rob Evans, geologist and member of the Society, has provided to the Lincolnshire Tree Awareness Group (TAG) information about the 9 Yews at Six Hills on the Lincolnshire Wolds, which are reputed to be associated with the grave of Gwladus, the cousin of Gwenllian. This information, with a photograph and line drawing of the yews, has been incorporated into the legends section of a TAG booklet on '40 Special Trees of Lincolnshire' published in September 2009.
