Dianne, I wrote John 1856 not 1865. He's in both 1871 & 1881 census. You really have to work to milk every ounce of information out of these records. I presume you've used census records other than the free 1881 at Family Search. If you don't have an Ancestry subscription, they may be available at a local library or FHS centre. Otherwise you can pay per view at sites like Find My Past. My guess is that Margaret was still alive in 1901 and possibly 1911. You should check those census records for additional information. The IFHF website has an 1855 marriage in Co Antrim for Hugh Heaney. Unfortunately, I can't tell you the bride because it's a pay site and would cost five pounds. Besides, as a professional researcher, there is only so much help that I can offer free of charge. A detailed answer to a tricky list posting does not come without a deal of research and looking up BDM, census and similar records. And most of the time, we are starting from scratch. Peter
