Based on her age at the census returns of 1851/1861/1871/1881, I have calculated she was born some time in 1814, but that could be a year out depending on the date of census. Only three of her sons moved to the Rhondda, namely John; David (my great grandfather) and Samuel. She died 19 December 1886 in Blaenllechau, Rhondda. There were 8 children, Elizabeth; Edward; Henry; Jane and William. Sorry I can't help more, with dates.
