Hiya,
I'm a little further on with the William John Poots marriage issue, though it's just getting increasingly confusing!
Going by the census of 1901 and matching up kids names and then corresponding burial records and address records, I'm pretty much sure that the William John Poots is the older one who married Eliza Mckeweon (who then remarried and became Eliza Wright). I've been in Banbridge this week and with the help of a lovely genealogy guy called Jason at the Banbridge tourist information (btw they have a family history section where you can make appointments and they have some of the general records information, like cause of death etc) he helped me find all the children of this particular William John Poots of Banbridge. He had 3 children before his second marriage - William John, Margaret Jane and Annie. BUT - their mother is not listed as Mary Lannigan, it's listed as Mary Poots Scott. There's also 5 years between the birth of the first child we found (William John born 1869) and the marriage to Mary Lannigan.
We've found absolutely nothing on Mary Lannigan prior to her marriage, but there is a Mary Poots who died in 1881 in Banbridge, who could be the wife?
Could Mary Lannigan and Mary Poots Scott be the same person?
Or could William John Poots have married two seperate women called Mary and then married Eliza?
If anyone could help, I'd greatly appreciate it.
