Well done Jackie Paper, it is the War Memorial of those two villages, situated roughly between them.
Dedicated on 9th April 1921, there is a contemporary account and photo on the village website Doddington, Kent. (Note that other Doddingtons are available).
The parishes are intertwined, where I live to the south of Doddington, there was a lump of Newnham separating our island of Doddington from the village, and from memory (unreliable at best) the south side of at least part of Doddington Street was in the parish of Newnham.
I did research a lot of this a few years ago when my early steps in Ancestry led me to discover that my paternal ancestors were from Doddington and nearby Wychling. My great great grandfather was born in 1825 in a house that I can see from our upstairs window!
Over to you….
