Good morning people,
I notice the boarding school for Robert J Molison b1869 Holloway, is Lancing. I take it this Lancing college, Sussex. Worthing is about 5 mls away (Broadwater and all). I'm often at Lancing and can take a look for any other member of the family that boarded at the "college" as well.
Do we have any other names?
Lesanne. 
Lesanne, the 1881 transcription on FamilySearch is pretty dreadful ('Colligate School'!) but there's obviously a brother of Robert's - transcribed as Salton MOLIS...! His forename is clearly Saltoun on the image though the end of his surname is a bit messy.
So we now have two of the sons of James MOLISON ('half-brother' of "our" Alexander Strachan MOLISON) boarding at Lancing - one b Sydney and one (after they'd escaped the fallout of the great explosion!!) b Holloway:
Lancing Sussex
Collegiate SchoolBoarders include "our":
Saltoun MOLISON, Boarder, 16, Scholar, b Sydney NSWWe hadn't picked him up before due to the rotten transcriptionAnd his brother
Robert MOLISON, Boarder, 12, Scholar, b Holloway
We've had him previously - see my post on page 48 for this and for the birth of Saltoun and others in SydneyJAP
PS: I had a friend here in Australia who, as a boy, used regularly to travel alone to and from Athens to Lancing in the 1930s to board at the College. Boat to Marseilles, train to Calais, cross the channel, train to Sussex ...
