Hi Tracy
Firstly, Cerrigydrudion is not in Gwyddelwern. It is a separate parish to the north of the parish of Llanfawr/Llanfor. Details of it can be found here:
http://www.genuki.org.uk/big/wal/DEN/Cerrigydrudion/index.htmlI think it might be worth you having a read through all of the appropriate pages on Genuki - most of the Denbighshhire ones have a map link. Also, have a look at many of the map resources online - including the old-maps site.
Gwyddelwern:
Baptism - Jan 13 1809 Margaret d/o William Jones (farmer) and Elizabeth, Ty Mawr
The only place that I can see in the records that comes near to the
Druid in Gwyddelwern (as the entry implies it is) is Ddwyryd. Check the old-maps site for it's location. It might take a while as you will have to pan around the Gwyddelwern area but, as the maps are available on line, I think you ought to do this for yourself.
Llanfawr/Llanfor:
The only Ellis Jones having children around the time was this entry:
13 August 1806 Jane D/o Ellis Jones and Lydia, living in the village of Llanfawr/Llanfor itself.
These might be Robert's parents.
