We all need a computer tech son, I have one too. Would love to see the photo c1880 as at that time the Ligertwood family were living there. The other photographs show what a beautiful house it must have been at one time. Thanks also for the gravestone photos, It also confirms 'the infant son' sadly not given a name.
I think the exterior photo you posted shows the outside staircase leading to the upstairs accommodation following its conversion to flats, I believe this is where the wedding photograph was taken in 1890.
I note too that the house was owned by the Welbeck Estates.. such a coincidence as the Welbeck Estate and Abbey are about 20 minute drive from where we live, we visit the Farm Shop regularly. Also to add to coincidence my husband worked for the Worksop Manor Farms which are associated with the Welbeck Estate along with Clumber and Thorsby, these four are classed as the Dukeries, being four adjacent Ducal seats.

Isn't family history full of surprises, I find it fascinating.
So pleased you found my posting.
