Hello, I've just noticed you were looking for a connection between George Catterick and his stepson George Kilburn. My connection is through the Catterick side BUT I have a marriage between George Catterick and Jane Kilburn at Leeds Registered Building in 1860. This would make sense as George Catterick's brother, Francis, was also in Leeds at this time and married there in 1867. There was also a marriage for a William Catterick in 1864, which I think was another brother so perhaps this Leeds wedding for Jane Kilburn is the one you are looking for. I found the information on YorkshireBMD so perhaps you could look on that for Jane's death. Hope this helps. Ena
