Hi.
Sans Souci Lodge was more than likely the gate lodge to Sans Souci House. Your relative may have worked for the owners of the Big House, perhaps as a gardener. When I was a kid there were still a number of gate lodges still about the Malone Road. Only one I can think of that's still standing is across the road from Sans Souci, on the left corner of Derryvolgie Ave.
Holyrood House next to Sans Souci also had a lodge, but I think it's long gone since Queen's University built their Halls of Residence there.
