I searched the Flaxgrower's List 1796 and found the following list of Hutchinson's who were growing flax on their lands in Derry:
There is likely to be some relatives of George on this list. Do any names of the parishes in this list stand out to you, that you may have come across before? I think Artrea is a parish close to Magherafelt.
I also checked the applications for Old Age Pensions and we seem to be in luck:
This here is an explanation of how the 1841 and 1851 census search forms (later destroyed in a fire in 1922) were used for Old Age Pension applications:
The William Hutchinson listed as George's father on the census search form is likely the same William Hutchinson growing flax in 1796 in Dunboe and Desertmartin, Londonderry. The Hutchinsons growing in the same area, ie Esther, Widow Jane, John, are very likely close relatives. It appears George had a brother called John, who also applied for a pension:
Do you know if George ever lived or was linked to the townland of Ballymoney in Londonderry. He appears in two directories on the subscription site www.findmypast.ie as from the townland.
Right, so in Griffiths Valuation, there is one Hutchinson in the parish of Magherafelt:
However, in the townland of Ballygurk in the nearby parish of Tamlaght, which is mentioned on George's pension slip, there is four Hutchinsons:
The Hutchinson's landlord is listed as "Worshipful Company of Salters":
I haven't been able to find much on Margaret Thompson yet, but I'll keep looking. Possibly more to come on George also. Hope some of this so far helps and if you have any questions on the documents or things you want to look for, ask away!
All the best,
