Hi all
I'm asking for help again with this search.
After making a lot of progress last time (aided and guided by Hume24) I still haven't a clue where in Ireland my Irwins/Irvines came from originally. I have several possibilities in Antrim but the key to this is finding the name of the husband of Ellen Irvine who is listed in 1861 with her family:-
Residence: 15 College St Back Land, Glasgow, Lanarkshire
Ellen Irvine, f, head, 60, househol[d]er, Ireland
Mary ", f, dau., widow, 30, mill worker, Ireland
James ", m, son, 25, puddler iron foundry, Ireland
Elizabeth ", f, dau., 23, mill worker, Ireland
Catherine Coligand, f, g-dau., 7, Glasgow, Lanark
Mary McCaskill, f, g-dau., 1, -, Glasgow, Lanark
I've hunted high and low for Ellen's death and just can't find it

. I'm presuming her death cert. would have her husband's name and her maiden name on it (which would open up a whole new branch in Ireland as well).
Can anybody advise what would be the next best thing after unsuccessfully searching SP records? (I found one in 1888 but she was Scottish and single and in Kirkudbright).
I've also used quite a few credits viewing marriages for Ellen's daughter Elizabeth but they all have different mothers and wrong ages.
Daughter Mary I now believe to be daughter-in-law to Ellen and mother of Catherine Coligand. Catherine's name I found out is McColigan. I have her birth and parents 1851 marriage (James McColigan and Mary Irvine) and her father's death in 1856. Catherine ended up in the City poorhouse through 1871 and 1881. Unfortunately Mary's marriage 'cert'. from 1851 gives very little information.
Any help or advice would be gratefully accepted.
Thanks

Tony
