They have postal address of Alberta Crescent which is a private road. I suspect there may have been or be a driveway to Alberta Cr which has become over grown. Anyhow Alberta Cr  (built before 1924) predates Priory Lane by a few decades. Priory Lane used to be Horse Common Lane to a field on the 1924 O/Smap. Alberta Cr extended more to the Priory Rd Junction then.
