At the Police Court yesterday, before Messrs L. E. Chambers, P.M , and G. P. Sinclair, J.P., Albert Eady, aged 12, and Cecil Barry, aged 10, pleaded guilty to having stolen 14s 6d from the hut of Albert Clarke on April 14 last......On April 6 tbe mother gave birth to triplets and the robbery took place on the 14th. It was evident that she could not look after him at that time. ......They would not be sent to gaol, but they would have to go to a place where they would be taught a trade and to be honest in the future. They would each be sent to the Training School for a period of four years.
Is the name change because Cecil Barry stole some money and the family left Tasmania and moved to Victoria before Cecil served his time at the Training school.
Can you also look at the triplets births please and see if the other triplet was given a name.Can only find 2 of the triplets names.
Did they have another child, named David Frederick Lawrence Byrne/Barry as I have found in the 1937, 1942 to 1968 Electroll Rolls.
