Hello Irene,
I only have a little info from the Shotton/Marson side of the family. I will ask if there are any Dillhorne photos, this will take a day or two, you know what farmers are like!
I should really give you all a little update.
Thanks entirely to the help from the chatters here, I did contact a family who live at Mow Top farm, they were a little shocked when I phoned them up, but very nice and polite. Unfortunately they did not know any thing about the previous occupants.
The uncanny thing is they are agricultural contractors, which is exactly the same as the farmer on whose behalf I am searching. Gave him quite a turn when I told him, so I have been waiting for him to show some interest before proceeding any further. I should think he has recovered by now, so will ask about the photos.
