Good Morning.
I think Robertsend was a bit further across .
If you go to Hanley Swan it is on the road going right towards Hanley Castle towards Horton Mill Farm.
In 1885 there are about 14 houses or cottages on the South side of the road labelled Roberts End.
https://maps.nls.uk/view/101586751To get the exact house you need the tithe map c 1830's which if they were living there then would give the exact property.
Unfortunately it's not yet on Worcester's free tithe map site but will be at the Archives.
https://gis.worcestershire.gov.uk/website/HanleyCastleMapping/Has some info but is a bit vague but does give owners of the land for 1797 .Apparently there is a 1852 parish map.
1797
parcel of land 197 William Jones house and orchard
461 next door Samuel Jones cottage and garden
Nothside
935 William Jones
331 William Jones pasture
330 William Jones ex Samuel Jones cottage and pasture
925 Edmund Jones Swan Inn.
In 1851 census the Weston are definitely at the right hand side of the Street near Holloway Farm perhaps just before Ivy House? 1903 ordnance map Chance Flowers just on the Northside after Holloway farm?

But it is one of those cottages next to the Farm
