Looking for Info on Edward George Madden of Belfast B 1841 D 12 Jul 1885 and His Wife Sarah Jane Herald

I'm trying to find out about my Great Grandparents, Edward George Madden and his wife, Sarah Jane Herald. They had 7 children who ended up in an orphanage. They were R.C. So I've heard they probably would have gone to Nazareth Lodge/ House. I know that Edward died in 1885 by falling off his roof while cutting an orange arch that was tied to his chimney. In newspaper articles (and there were many) it was estimated there were 3000 people that followed the funeral cortège to Milltown Cemetery. The newspapers also said he left a widow and 7 children. He lived at 83 Wall St.
