What changes did Nancy bring to the red house?

I personally thought she brought a bit of sadness to the house along with quite a bit of piety. She isn't a happy woman.....

Physical changes- from the text

"A great change has come over the dark wainscoted parlour since we saw it in Godfrey's bachelor days, and under the wifeless reign of the old Squire. Now all is polish, on which no yesterday's dust is ever allowed to rest, from the yard's width of oaken boards round the carpet, to the old Squire's gun and whips and walking-sticks, ranged on the stag's antlers above the mantelpiece. All other signs of sporting and outdoor occupation Nancy has removed to another room; but she has brought into the

Red House the habit of filial reverence, and preserves sacredly in a place of honour these relics of her husband's departed father. The tankards are on the side-table still, but the bossed silver is undimmed by handling, and there are no dregs to send forth unpleasant suggestions: the only prevailing scent is of the lavender and rose-leaves that fill the vases of Derbyshire spar. All is purity and order in this once dreary room, for, fifteen years ago, it was entered by a new presiding spirit."
