There are two Ulcebys (at least) - I guess you're talking about the one near Partney.
There are a couple of burials at Ulceby which may be relevant
Jonathan GRAVES 19 Sept 1850 aged 85
Elizabeth GRAVES 8 Jan 1832 aged 66
It's possible thay were the couple who had 3 sons baptised at Hundleby in the 1790s (about 5 miles from Ulceby).
