Hi Dave
The evidence I have for Mary Lunn nee Robson is as follows, (apart from a succession of middle names in the next two generations being Robson) I did a search of all Lunn / Harbottle related documents on the Northumberland Archives online. It had three relating to a property in Harbottle owned by the late James Lunn which I sent for copies. One is a very detailed description of the property and where it was in Harbottle, it seems to be a document dealing with the winding up of James Lunns affairs in 1850 after his death in 1949.The second was a description of the cottage with a sketch of the floor plan its ash privy and coal house. The third was the bonus, again a description of the house of the late former tenant James Lunn and its value £10.00, the cottage by 1850 was in a poor condition, towards the end of the document it relates previous occupants, "Robert Davison deceased, afterwards enjoyed by Marjory his widow, and now or late occupied by Mary Lunn, sister of the said Marjory to hold from AD 1827 at will. A Marjory Robson married Robert |Davison in Alwinton in 1779, hence Mary being Marjory's sister must also be Robson. Marjory Davison died in 1826 so her sister moved into her cottage but looks like Mary Lunn son James was paying the rent. Using the two sisters dates of birth there was a candidate family in the next village of Alwinton, father William Robson with a son also called William, who I suspect is the family witness to the three marriages as William senior died in 1808 and two other sons James and Edward,not the most direct evidence but going that far back it might be all there is available.
If you want Mary Lunn's signature or mark ' X' you can find a marriage licence for her daughter Mary Lunn to Adam Sheills on line in the FamilySearch site.
I need to correct my last post I said that William Robson was from Whotton, this is incorrect it is Whitlees in the Elsdon Parish.
As my interest is in the maternal line, my next step is to find a name for William Robsons wife, Mary Lunn's mother and the evidence to prove it, there was a Margaret Robson wife of a William Robson who died in Harbottle, buried in Alwinton in 1798 but I need more evidence..but that's the fun bit!
if i can be of any help just ask. Bye for now
