I have seen the bing birdseye view of the children's homes Georgeville and Maryville (please note they were not orphanages). The view clearly shows the identical ends of the semidetached building amongst the trees. The flat roofed building, to the right, did not exist in the 1940's.
It is most unlikely that your father was in Georgeville. All the boys in Georgeville and Maryville were of school age.
In 1942 (aged 9) I was admitted to Maryville until 1948. My younger brother (aged 4) was admitted to the Views and transferred to Georgeville, at the age of 5, when he became of school age. My youngest brother (aged 9 months) was admitted to Jorden House nursery and adopted when he was 2 years old. There were no facilities for infants in either Georgeville or Maryville.
Children were rarely fostered and even more rarely adopted, remember this was wartime. I can only speak for boys, who when they reached school leaving age, often went to work in Black Dyke Mills near Bradford, mainly because the mill owners provided hostel accommodation.
Georgeville, Maryviille, Ashley House, The Views and Jordon House nursery were managed by the Housing dept. of and on behalf of Barnsley Borough Council, and day to day running was the responsibility of the Master of the Poor Law workhouse.
Whilst this does not answer your queries I trust it may be of interest
