Hi, I descend from Patrick Hegarty and Mary Dillon of Brockaghbuoy. She was never Mary Anne, by the way, that must be a mistake in the records. My grandfather was born in the "Blackhill" Brockaghbuoy, and my uncle owns Patrick Hegarty and Mary Dillon's farm there now. The Blackhill is a name for a specific area within the townland of Brockaghbuoy, situated, not surprisingly, at the top of a hill. Your ancestor Daniel had at least one other brother Michael born 30th Nov 1861, but perhaps he died as an infant. I am going to email a cousin of mine who has done a lot of research into Brockaghbouy families, I know that she has the names of Mary Ann McNicholl's parents anyway. I imagine that she will comment here when she gets time. We are probably distantly related, both descending from Hegartys from Broackaghbuoy! Out of interest, where did you here the name "The Blackhill"? It is a word of mouth term, not an official one, so only locals would really know where it is.
