My gran was Rose Jones (Llewellyn) and her mother was Annie Laurie Dovell. I have been researching 'our' family tree for some time and have alot of information including a photo of Annie with her 3rd husband and details of all her marriages and death. I, like you, cannot find her birth or details of her parents although i do have a copy of her marriage certificate to Thomas William Llewellyn in 1897 which gives her fathers name as John Dovell. I Won't bore you with all the details but if you still use this site get in touch and i can let you know what i have and you can do likewise.
All the best....Chris.
