Hi Kate,
I've been researching for many years and had great difficulty with my gt gt grandfathers wife,on census records it only gives the christian name of the wife,obviously as she is now married,was fortunate just recently to come across some new records and my gt gt grandfather married a Isabella Hornsby in 1847 in the Easington district,Monk Hesleden,my gt gt grandfather was Matthew Stelling,they eventually settled in Willington nr Crook.
Isabella's father was a George Hornsby and Mother was named Jane possibly Blair,Isabella was born 5th october 1828,in the i.g.i info is given that says a George Hornsby married Jane Blair on 3rd April 1809 at Houghton-le-spring.
There ia also a birth for George Hornsby on 7th december 1788 Father Richard.
As I was researching Hornsby I found very few in County Durham for that period of time so perhaps this may be of some help,let me know if I can help out in any way,
Regards Mikayla
