I’ve done grave finding in the past, once with a well known field sport author and the other with Brait Wilson, former whip and huntsman of the ullswater FH. They weren’t so difficult. I just tracked down to where their final abode was and searched locally, through registrars and graveyards. Most will have a list of who’s buried where. If the graveyard was small I searched it myself. It’s a great thrill to finally find something like that, good luck in your search ??
