I think there may be another possibility.
Joebhoy has given the details of your Charles at Middleburn, Eskdalemuir in 1841. Also at Middleburn, but in a different household, were:-
Margaret Dixon 74 Pauper
Elizabeth Dixon 37 Ag Lab
Margaret Murray 19 Ag Lab
Mary Johnston 6
All were born in Dumfriesshire
Moving to 1851, still at Middleburn:
Margaret Dickson Head W 84 Pauper (formerly Servant)
Elizabeth Dickson Dau U 48 carrier
Margaret Murray GDau U 28 Employed in House
Mary Johnston GDau U 16 Employed in House
All were born in Eskdalemuir
However, also at Middleburn in 1851, were:
Charles Dickson Head Widr 65 Ag Labourer
Janet Dickson Dau U 40 Employed in house
John Dickson Son U 33 Ag Labourer
James Dickson Son U 31 Ag Labourer
Christopher Irving Grson 7 Scholar
All the adults were born in Eskdalemuir, Christopher was born in England.
I don't believe Middleburn is on recent OS maps but the Grid Reference is/was NY258974. It is on
www.old-maps.co.ukI THINK Fingland - the home of Jean Little in 1851 - should have in fact been Eskdalemuir not Canonbie.
In 1841 there is also a Jean Little at Fingland with Alexandr Welsh who was 65 and an AgLab. Her age is given as 'not known'. Both were born in Dumfrieshire. In 1851 Jean Little was on her own at Fingland as Joebhoy described.
But how does one rationalise the Jean Little at Middleburn in 1841 with the Jean Little 'up the valley' at Fingland also in 1841? In 1851 Charles Dickson was a widower indicating that his wife (Jean Little?) had died. It would appear the Jean Little at Fingland was not connected with AD's Charles at all.
For now
