Thanks for that. Think the John of 1841 census sounds like my familys john as on his marriage cert it said master mason. Not sure why it also said ferryton cottage unless his parents ( and where was his dad on the 1841 census) had moved or suppose it could have been his wifes house, that sounds more feasible. Can see why you call yourself sherlock, its certainly detective work. Am unsure about Francis as so far if it was my John thought his siblings were ann and james who would have been 25 and 19 respectively at the time of the census, so wonder were they lived.
Thanks again.
