Hi Warnecke and welcome. Yes I have that certificate and the surname is Hearles. It has also been listed as Arls in the 1841 census. Sadly William C Mitchell passed away in 1856 due to a mining accident (fall of earth)/ Happy to exchange information with you.
Hi CT and all my Cornish cousins. Just popping in to see how you all are and no I haven't found Edward (1818), Samuel (1822), or Elizabeth Michell (1832) as yet. I have been banging my head against other family tree brick walls. I hope to find out more about Eliza Hosking (nee Michell) and her son William John soon. Cheers
