Hi Jeannette,

From the 1851 census index I see:

Bennet, Helen aged 34 b. Kinross, living in Kinross

seems to be living with:

Bennet, John aged aged 41 b. Portmoak
William aged 1 b.Kinross
Robert aged 11 b. Kinross
John aged 12 b. Kinross
James aged 6 b. Kinross
Isabella aged 9 b. Kinross
Helen aged 14 b. Kinross

There is also a John and Elisabeth living together:
John aged 82 b. Portmoak
Elisabeth aged 80 b. Leslie, Fife

There also could be a grand/son Alexander aged 37 there too.

Robert and Isabella Graham:

Graham, Robert aged 69 b. Orwell living in Kinross
Graham, Isabella aged 62 b. Kinross

From the same schedule there appears to be a son
John, aged 24 b.Kinross
James, aged 28 b. Kinross
Elisabeth, aged 38 b.Kinross
