The Cornwall brothers who established their ranch, "Ashcroft" in 1862, came originally from the village of Ashcroft in Gloucestershire, where their father had been vicar. When the CPR adopted the name Ashcroft for their station just east of the ranch (and what would become the townsite), the Cornwall's added "Manor" to the name of their home, making it Ashcroft Manor. See also the municipality's website.
