Well, it seems that my knowledge of English counties and geography is woefully inadequate.
The 1891 census you found in Hunslet, Yorkshire I believe is my family and not the Robert in Northamptonshire. I am not sure how I got so off course.
The presents of Mary Frampton in this household seals the deal. My grandfather was known as George Frampton Swailes and he was born in Yeadon, Yorkshire.
Now any chance we can find out what their address was in 1901?
Many thanks
