Sadly not. All we know is that his eldest child Richard (well eldest found thus far) was born in Llandysilio circa 1827; the two later daughters Jane and Catherine in Llanfihangel.
John was living with his two daughters and a wife (presumably) Ann at Ty Pen y Capel according to the 1841 census. We believe Anne may have been a second wife but cannot be sure at this stage.
Thanks for your interest.
