You may also be interested in Briant Dell's grave (Richard's brother). The two graves are only about 40 yards apart. Briant's isn't marked with any memorial - but it is immediately to the right hand side of the kerbed grave (on the left of this picture).
In their final years, the two brothers lived just a few hundred yards apart. Briant's home was in Northcote Road (picture herewith).
Fascinated to hear about the taboo.
