This Alice Spencer is the mother of Clarice May, as well as the wife of John May. However, I found another Alice Spencer record showing her birth in Doynton, Gloucestershire (near Chipping Sodbury) in the same birth year (but received baptism in February), with her parents listed as Guy Spencer and Thirza Hall.
I'm not quite sure if those records are of the same Alice Spencer. Feel free to give me feedback!
