tom had been buried so long ago that his stone was just a weathered rock , and he had lived and died during the hundred years war with france , while miss euphemia ( 1861-1883 , she sleeps , aye , yet she sleeps with angels ) had been buried in victorian times , after the graveyard had been expanded and extended and became , for some fifty years , a successful commercial enterprise , and she had a whole tomb to herself behind a black door in the willow walk .
