Lesandfred on Family Tree Circles

My Gt2 grandfather was Mayes, married a Rebecca (thought to be Church)(born 1825/6) in Huntingdonshire. They had 2 children, Alfred (1849/50) and Elizabeth, both born in the Crew area. Gt2 Mayes we believe was then killed in a forge accident and Rebecca remarried (1852-5)one George Smith and had a new family.
I can find no trace of the death in the usual archives, nor his birth - and only one reference to a possible name (Edward).
Can anyone help, please?
