Essendon where William Beckley was the superintendent (See Beckley, Orphanage at Essendon, 1873) In answering the query I pointed out that Letitia Georgii was the matron in the 1881 census.
Jennifer has now provided the following additional information:
I have been researching the Georgii family for a relative.Letitia Georgii nee Hill was married in London in 1866 to Thomas Georgii a book binder. They had 4 children but by 1881 the marriage seems to have broken down. As you know Letitia was Matron of the Boys Home and her son Thomas was living with her. Her 3 other children were in orphanages; 13-year-old daughter Alice in Marylebone, and sons Frank (6) & Frederick (4) in Torquay. After some difficulty I found Letitia's husband boarding with a family in Ealing.
