Thanks for looking Kiterunner
A few years ago I hired the LDS film for Enford parish registers & I made no note of the submitted baptism entry, or the possible marriage and burial that you've found. But at that time I'd only just started on this line, so quite possibly missed those entries whilst looking for many other names. I will go and look at the census entries you've found and make a note of the possibilities.
Interestingly, I have a family of Sellwoods (also from Charlton) marrying into another of my Wiltshire lines. Not that unusual though, most of my Wiltshire side didn't travel far and intermarried quite a lot
