He was given an MBE in the 2012 Queen’s Birthday Honours for his services to the community in Aberdour, Fife, where he worked as a station master.
Now Francis has been warned he faces a jail term when he returns to Dundee Sheriff Court to be sentenced next month.
Three girls – aged 14 to 16 at the time- told a jury that Francis would creep into the girls’ dormitory at the home in the night and sexually assault them.
One told how he touched her on the chest under her bedsheets while another said he had touched her genitals under her covers.
A male resident at the home told how he had once run away and got as far as Kirkcaldy where he was picked up by police and taken back.
Francis took him into a laundry room and attacked him as punishment.
Other victims told how Francis slapped them in the face and beat them with a slipper in violent rages.
Francis, 71, of Manse Street, Aberdour, Fife, denied a total of nine charges on indictment.
However, a jury of eight men and seven women took two and a half hours to find him guilty by majority of two offences of using lewd, indecent and libidinous practices and behaviour towards young girls and three assaults.
