The Dorking reference could be an error based on the 'The Battle of Dorking' (written in the 1870's, about a German invasion of Britain), which is said to have inspired HG Wells when writing 'The War of the Worlds'.
I can understand if the story is adapted to keep to a single narrator (unlike the book, where it shifts between the two brothers narrating the story) and to introduce some more characters and events to pad it out (it's a very short book), specifically more rounded female ones, so long as they don't spoil the overall narrative. In the book the two women encountered are rather clichéd by modern standards as damsels in distress and, although possibly accurate to the period, probably wouldn't be greeted with much enthusiasm today.
