You are right John HOWLETT is hard to find 1881 conclusively.
So the best idea is to buy the 1883 Marriage Cert.
But you can look for Georgiana HARDIMAN, born abt 1854, Carlton Rode, Norfolk.
Another way to find her is look for Alice , born 1878, Bunwell.
Maybe is she is a Howlett John was married before too?
I'll look as well but it is good if you learn to search yourself.
