There are three Curtois graves behind the small church at Langrick in the Lincolnshire fens. Peregrine Samuel Curtois and his wife Rachel share a well preserved one underneath a yew tree, and next door but one, and much more weatherbeaten, is his sister, Martha Susanna Grant. There are several more Grants in the vicinity, including some Johns, but I don't know which (if any) is her husband.
