Dear Both
This is looking very positive. I did indeed make a typo on the original email, and have been looking on family search org for a Ms Margaret Jones/Davies 1822 for sometime but never turned up this record. Are these newly released records? anyway I am hopeful I can come up with something now.
With regards to the 1841 census never anything, however I didn't have much to go on. It is odd that Margaret in Yspyty, as it is quite a distance, so I was checking farms in this area to see if she was a servant. As she was married in 1842 I thought that she may have moved alone earlier, due to the distance, before she met Owen Roberts.
Although I realise it may not be the one, it is something I can at least research so many many thanks Lucinda
