An exhibition covering the gentry and aristocracy in the county is running at a museum in Kettering.
Family Fortunes is open to the public at the Manor House Museum, in Sheep Street, until January 28.
It focuses largely on three local families linked through marriage and circumstance.
They are the Treshams, the Montagues and the Brudenells.
The exhibition is the brainchild of historian Delia Thomas, who is also doing a talk on the Tresham family at Alfred East Art Gallery at 1pm on January 11.
Museum officer Eleanor Baumber: “It is interesting because it not only takes a look at each of the families but compares what they each did during the period.
“Many people will recognise the impact they had on our towns, much of it by the style of buildings each left behind.
“So far we’ve had many people come along and the feedback has been good.”
Family characters examined include Sir Thomas Tresham, a former High Sheriff of Northamptonshire, who is perhaps best known for creating the still unfinished Lyveden New Bield.
