The great thing about local history is its different facets, particularly the social aspect. It can be fascinating analysing the census returns. For example, on the 1901 census, Holly Bank, the big house identified by diggingdeeper as being on the old Mount Primary site had six residents who were looked after by four live-in sevants! Of the ten living there only one had been born in Wallasey - indicative of the huge influx of people into the area in the late 19th century.
Nudge, I've attached copies of the 1901 census covering the big houses in Mount Road. If you can't read them properly (I think there's a way to enlarge them but I don't know how!) let me know and I'll arrange for them to be dropped in at school if they are of any interest.
Incidentally, my grand daughter is an ex-pupil of Mount Primary and her interest in local history started with some of the projects she was involved in there. So much so that a recent project she did at Oldershaw on the Guide Dogs for the Blind Association has been placed on the .. site that diggingdeeper put you in touch with. Keep up the good work!
