Hi Ronald,
I am researching the history of Cwmamman and have a few pages on the following site which will probably be of interest to you:
http://www.cwmammanhistory.co.uk/The "Brynlloi Farm","Ty-Llwyd" and "Gwenllian Morgan-Phillips" pages should be of particular interest to you.
Most of the Family are buried at Hen Fethel, Glanamman and have strong associations with the chapel. The Morgan family resided at the original Brynlloi Farm at Glanamman, built c.1600 and demiloshed in 1906.
Morgan Morgan resided at Ty Llwyd, Glanamman. He built Christchurch and the vicarage in Garnant.
Some members of the Morgan family emigrated to the USA. (Though, through marriage, the surnames became Thomas, or Morgan-Phillips).
If you require any further info, you may Email me via the link from the homepage of above website.
Good luck with your research,
Dave.
