I’ve found something rather fun on Google Books – Suckling’s Memorials etc of Essex, published in 1845. He went round many of the parish churches of Essex, recording memorial inscriptions inside the churches, reproduced brasses, and takes includes information from Morant’s books as well.
And aside from all of that, there’s some lovely illustrations of some of the churches too – such as this one, of Greensted near Ongar. It’s a lovely image, with an almost-empty graveyard! As well as figures in the images – some might be your ancestors, perhaps! There’s sketches of the interiors too, some of which might look quite different now, and some which have barely changed (except for the tea urn and biscuit tin at the back!).
Do take a look.
