Thanks Gibel.
It appears Walter Tofts died in 1890, and in 1892 Florence remarried to a John Tofts.
And sadly in regards to daughter Kate, there is this:
Grantham Journal 12 March 1904
Sad Fatality
A verdict of "Accidental death" was returned on Saturday, at an inquest on Kate Elizabeth Tofts, aged eighteen. the deceased and her fiancee were being driven by her step-father, Mr. John Tofts, of the Catherine Wheel Inn, Albury, to Bishop Stortford station, when the horse shied at a stationary motorcar. All were thrown out, and rendered unconscious, and Miss Tofts succumbed to concussion of the brain.
