Hi,
I'm also checking out this line and re-examining the likelihood of Thomas being the George Thomas Fozard b.1818 with parents John and Sarah Scott, I'm not convinced as there are a few oddities, i.e. two sons called George, when the first is still alive and well and later married with his own family!
After ages searching everything I can think of I've got two possible sets of parents for this Thomas;
Thomas Fozard- parents John b.1799 and Ruth Varey/Varley b.1800 who marry on 25th Dec 1822 at Woodkirk, Yorks but their son Thomas is christened in 1825 (?born years earlier)and according to one personal site, if correct, marries a Lydia ?Fothergill and has a family-'our' Thomas is married for life to Hannah Jagger.
Next Thomas Fozard has parents John and Elizabeth Blakey who marry 4th dec 1820 at St Peters, Leeds, I think they are the most likely, but I can't find anything else out about them, they seem to disappear, but maybe noone has followed this line of Fozards specifically before us!
Have you looked into these people before and do you have any info you could share?.....please. Any help would be great. Thanks and best wishes.
