Thanks for the info Mike, much appreciated.
Not sure how I'll pursue my research next. Looking forward Thomas Curry and family moved to Lincoln / Sleaford for the 1841 census but were back in Leicester in 1851, however, Thomas had died in January 1851 in Lincoln.
I think there are some inconsistencies with the births of their children which I need to check as there seems to be some 'toing and froing' between Leicester and Lincoln.
Can't find George Currey or Sarah on 1841 census or beyond.
Think I'll stuggle to figure out where Thomas was born he was a stonemason so he learnt his trade somehow, possibly from his father...
thanks
Mark
