Thanks Manchester Rambler

That's my lot
I've gone back to the 1881 and found Thomas still at home with hs parents William and Ann Spare.
William is a publican of the Holly Bush pub in Kingsbury Warwickshire, and was born in Baddesley Warwickshire abt.1817. (There is another brother not on the 1881 - William who was also born in Yorkshire in 1854).
I know William and Ann were in Cornwall during the 1851 census and I know there are a lot of Spares in Cornwall so I suspect my lot may have originated there.
One other thing - Ann cannot decide where she was born - she has said Carlisle, Ireland and Dudson in Cornwall on three different census!!

.
The thing is I can't find any reference to William's birth in the IGI - born about 1817 - does anyone have any ideas how I can get further back?
Thanks
