This is really odd.
In Hollingbourne in Mar 1874,Caroline appears to remarry.
The 4 names on the page are...
Mary Ann BATES
Charles EVEREST
John HONEYSETT
Caroline WAGHORN
So trying them in 1881,finds at Stone House,Headcorn.
John Honeysett head 59 ag lab b Headcorn
Mary A Honeysett wife 36 b Smarden
Charles
Waghorn 12 son in law (usually meaning step son) scholar b East Sutton
Ben S Croucher son in law 10 scholar b Frittenden
Next question is who said they were related to Mary or John? Did the enumerator just presume it?
Maybe Charles couldn't stand this new step dad- old enough to be his grandad

and that's why he ran away?
Hmmmmmm,and what happened to Caroline and Charles.
Carol
