There is this: if you have ancestors who have featured in Court, and I mean the criminal rather than the royal ones, it must make it a bit easier to find them. As far as I know, none of mine have, so in the 1861 census, when several are missing, it's a nuisance to try to seek them out.
It also makes a change from my unrelenting trudge of carpenters / farmers/ tradesmen, and gives you far better stories to hang on your trees.
You are fortunate, those of you with Crimrelatives!!
