another possible for the place of birth is Robleston in the parish of Camrose.
http://www.rootschat.com/links/01q8s/and there are Warlows in the area. In particular, William & Sarah Warlow having children baptised
Ann 22 April 1810
Martha 14 March 1813
Thomas 23 April 1815
William 5 April 1818
Sarah 8 June 1823
William Warlow married Sarah Mabe 4 June 1807 in Camrose, the witnesses were James Thomas & Stephen Mabe.
There's a bit of a gap between the marriage and the baptism of Ann, possibly room for a Stephen baptised in a church whose registers aren't online?
