Hello Dave
Thanks. Don't quite follow yet.
The only thing I know about Mary JACKSON (retired Tanner 1851) of Gowthorpe, Selby, was that she was born GRANTHAM, Lincolnshire about 1786.
In 1861 her Daughter was Mary JACKSON, born ACKWORTH, Yorkshire, living with her, at Gowthorpe, Selby.
In 1861 Sarah HOOD, Tanner, age 41, Widow, born Selby, was living adjacent to Mary Jackson and her Daughter, Mary Jackson.
