I see that Emma and some siblings are step-children of Edwin Walden or Walder in the 1891 census - he is with an Emma born c1859, Surrey Chelse??
The oldest child is Millicent Titch*, born c1882, Brighton ... the youngest Clara, c1887.
There are 2 Walmer kids, aged 2 and the other 6 months, so that helps to look for a marriage of Edwin & Emma.

In 1901, the Titch* kids have taken the Walder/n name and Mum Emma more clearly states Chelsea as her PoB
