Sorry there's a piece of a sentence missing!!
In the Ivorites Eisteddfod to be held in March 1851,
there was acompetiton to write a verse of praise, sung to the tune 'Calon y Ddwerwen, ' to John Phillips of Gwaelod y Garth for his faithfulness in favour of the Ivorites and the fact that he was a father of 8 sons, in the Illltyd Sant Lodge.
The Ivorites met at the Colliers Arms, near Garth Hill House and were still meeting there in 1893 when a William Phillips accepted a presentation on behalf of his brother John Phillips ex secrertary, who was too ill to attend.
https://newspapers.library.wales/view/4596214/4596219/39/ I don't know if these 2 Phillipses are sons of John senior. There doesn't seem to be a John in with the rest of the family in a census, but the Eisteddfod competition states he had 8 sons.
There's a baptism for a John Phillip reputed son of John Phillips by Gwenllian Llewelin was baptised at Ystradyfodwg on 21 Sep 1806.
