With some help I now know a little more about 58 Queens Road Watford. This is where I believe George Goodman son of George, my great grand father, was living in 1891. His mother, who was a widow by then, may have returned to Ireland.
In 1887 Sisters of The Third Order of St Dominic, at Harrow on the hill, bought a a site in Queens Road Watford Herts. They built a convent and orphanage. 58 Queens Road became St Vincent's Boys Home and 64 Queen's Road, Westgate House, became St Vincent's Convent. In 1892 the Dominican sisters sold their site in Queens Road and purchased a site in the newly developed Percy Road Watford adjacent to the Holy Rood Catholic Church. In 1893 the new premises housed both the convent and their girls school and was then enlarged by the building of a St. Catherine's House for Boys. The girls school appeared to be private. Quite separately, a Board School was started for Catholic children with entirely lay staff, with the parish priest as the Reverend Manager.
George's mother was a Catholic therefore on the 1891 census at 58 Queens Road this does look like George. I hope this information may assist someone else as I had previously looked at info re St Catherine's House for boys and had not associated it with 58 Queen's Road as the areas are not exactly close to each other.
