Dear Huwcyn,
Rev. J G Owen b.1850 died 1920 he was a Minister at Soar Chapel for over 40 years. If you can get hold of the book "A century of photographs" of Llangeler Parish which was published in June 2000 by Llangeler Community Council and printed by Gwasg Gomer, Llandysul, Ceredigion there is a photo of Rev J G Owen's funeral procession. I assume he was buried at Soar Cemetery, but next time we go down to put flowers on the graves of my parents and grandparents I will have a look for a grave and will take a photo for you. Be warned that if you do go to see Soar Chapel (the cemetery is quite a way away from the chapel, by car, and on a very narrow road). The old way of getting to the cemetery was by a track through the woods and a windy uphill trek (that's the way they used to take the horse and bier with coffin) this track starts fairly near the chapel, but it's walking only.
Soar Chapel is in Cwmpengraig (which is in the Parish of Penboyr). A huge amount of my relatives were members of Soar Chapel including my parents and grandparents.
The easiest way to find it, is if you go to Drefach Felindre (3 miles from Newcastle Emlyn) and at the village square you will find St Barnabas Church and the Primary School (next to each other - these to your right). This is the A484 and is the road to Carmarthen go over the little hump back bridge (just by the school) and pass the pub on your left (which is now called Tafarn John y Gwas and at the present time is bright yellow). Carry on up the road for around 2 miles or so then keep an eye out for a right turn ) and Soar Independent Chapel is just off the road your travelling on. The A484 is a narrow road.
Councillor R G Owen was one of Rev Owen's sons. Cllr R G Owen later became a Justice of Peace. He was also a Deacon and organist at Soar Chapel in 1947.
For info - Drefach Felindre was very industrious with a huge amount of Woollen Mills within the area during the time that Rev Owen was at Soar.
Hope the above helps a little,
Kind regards, Alltcafan
