Robyn, There may be a distant connection between us. My ggGrandfather was a Car(r)ington Aylward born around 1816 and christened in Greenwich, kent, then later married in St Nicholas church in Deptford Kent. The family thereafter was also associated with Bermondsey where I came from and where my aunt still lives. As you may know Deptford Greenwich and Bermondsey are now all very much part of metropolitan London but in those days were fairly closely spaced villages. I am still in the early phase of tracing my family tree, but when I am next in the family History centre in London I'll see if there is anything that links your P.W.Aylward with my Carrington (though you seem to have covered the obvious bases with the 1851 census).
