I get 471 'hits' for Browns in Northamptonshire that had Turland as either their first or middle name.
I'd look for family groups in the censuses 1841 to 1911, and try and figure-out where 'my' person fitted in, then look for parish, birth, marriage and death details, and go from there.
Newman Turland Brown abt 1839-1901, in Wollaston, Northamptonshire.
