Hello Nequine
George Street was demolished in the early 1970s. There was a school there called the Craigs School because it was also in a street known as The Craigs. To find George Street's whereabouts on a modern map look between Upper Craigs and Wellgreen Road. It was in there.
The Children's Home might have been the Whinwell Home. It was founded about 1880 by Annie Knight Croall, who ran it for many years then handed over its management to a Board of Trustees. Miss Croall died in 1927 but Whinwell continued until 1980. The Aberlour Trust bought the building but eventually sold to a property developer and the building was demolished and houses built in its place. All the records, including case notes, are with Stirling Council Archives. They have a contact email via Stirling Council website.
Best wishes
