I keep coming back to your message as its really " bugging" me - in a good way of course. The reason being, your William Craven Calvert....... I have a Grace Ann Calvert born 1895 ( father was John Calvert)who married John CRAVEN, born 1896. I have found none of there children yet but im working on it but they did live in Wakefield for a while. It is possible that that they had children and could have named them "Craven Calvert" I realise the dates are out and your william was born before my Grace so couldnt possibly be a child but im thinking its possible to be relations and maybe married cousins etc.......... Its all just ideas at the moment and theories but like i say the similarities and coincidences are there. My Ledger family also moved to Woolongong, so thats another little extra! Sorry all this vague but like i say im working on the Craven Calvert as im convinced it might join up somewhere............ At the moment im stuck on John Calvert, born 1775 in Guiseley, West Yorks, so im trying other lines now until something turns up!
Look forward to hearing from you,
Karen. West Yorkshire.
