I first heard a similar tale in Haiti, where it is believed that the first person buried in a churchyard will become its guardian, looking after those buried there to ensure that bokors do not use the body parts - or indeed the whole bodies - of the dead for evil purposes. This is also the origin of the legend of the Church Grim in both Celtic and Teutonic lore. It seems reasonable to imagine that the belief translated to Haitian Voudon through either French belief, or the superstitions of indentured servants brought from Ireland. Perhaps curiously, the Church Grim is not much part of New Orleans Voodoo lore.
In Northern France and the British Isles, the Church Grim was also considered a guardian of a churchyard but it came in the form of an animal, most often a black dog. The ancient belief that the first person buried in a churchyard would become its guardian led to concern for the soul of that dead person once Christianity took hold. How would they find their reward in Heaven - or punishment in Hell or Purgatory - if the soul was tied to earth? The solution was to bury an animal in the churchyard first, sometimes unfortunately while the poor thing was still alive, to have it take up the position of protector of the dead.
As noted, people of Celtic descent usually chose a dog for the duty; the larger and blacker the dog, the better. With the advent of Catholicism, the dog's duty expanded from guardian against witches and sorcerers to protector against the Devil. It was said that a churchyard that had a Grim was the best place to be buried, for the angry spirit of the dog would keep the Devil from dragging your soul off to Hell. Whether or not that meant you got a free pass to Heaven is left out of the folklore, however.
In Teutonic countries, the legend remained essentially the same but the animal differed. In Sweden, during the vary early days of Christianity, a lamb was sometimes slaughtered and buried under the altar stone of a new church. This lamb, often black, was from then on referred to as the kyrkogrim who defended the dead against the Devil. Meanwhile, in Denmark and Hanover, the Grim came in the form of a black, female pig. Known as the kirkegrim or "grave-sow" she did the same duty on her graveyard turf.
All of these sacrificial animals get a bit of their own back in the end. It was universally believed that seeing the Church Grim, and in Celtic countries hearing its howl or bark as well, was a certain sign that death awaited the beholder.
And that, you have to admit, is a pretty good story.
