Grace Elsie Wheeler (nee Hunt)
~ Marriage in Oxford, Oxfordshire, UK
Married Sydney F Capel after the death of her first husband, George Henry Wheller, in France on 3 September 1916 during the Battle of Thiepval, the Somme, France.
Her first marriage to George Henry Wheller was in Leeds in December 1915, a few months before he was killed in France.
Sounds close but I think they are different people.
