I'm trying to find out which property in the very small ( 14 houses !) hamlet of Wooperton, Northumbrland, near Alnwick.belonged to the Burdon family. Various websites and gazetteers list the name of the person i'm looking for but not the actually property and they have the entry :
Augustus Edward Burdon, Hartford Hall, R.S..O and Wooperton, R.S.O.
The period covered would be around 1880-1920.
What does R.S.O stand for, please?
