I only came across this thread yesterday, and am delighted as it appears to have solved a brickwall in my research that has troubled me for some time.
Harriet Bradley, recorded in the 1841 census, age 4, living with Thomas and Elizabeth Bradley, and in the 1851 census, age 14, the daughter of Thomas and Elizabeth Bradley, would appear to have become the Harriet Burrell, age 22 (father Thomas Burrell) who married Thomas Chapman on 25 Dec 1860 at East Bridgford St. Peter's.
Thomas and Harriet Chapman were my great-great-grandparents.
I'd be grateful for any further information on the Burrell/Bradley family, and particularly any explanation for the name change.
