Hi Deborah, the marriage took place in 1860 in Lordship, on Christmas Day, the parents christian names are not given so difficult to pinpoint the exact Eliazabeth, there ae 7 born in Louth in the period 1830 to 1843 which is most likely years, those born later would be too young to be married and I did not search further than 1830. If we could find her actualy age it would assist but really need the fathers name to pinpoint the correct person. Witness's Ellen McDermott and Bernard McGrath.
I see one baptism in 1830 is for Betty McDermott mother Conlon in Dundalk but as she married in Lordship I assume she was from there as that is the custom to marry in the brides parish. Oddly there are a numner of Elizabeth McDermott marriages in Lordship, an earlier one in 1852 and 1874 to a Charles Donnelly The 1852 marriage is not easlily discerible as to the husbands name but Peter Callan to me, witness's where a Thomas Rice and Rose McKenna.
I assumed Ellen McDermott was her sister and found an 1874 marriage in Lordship to a Daniel Byrne, unfortunately this marriage does not appear to be in the civil register so not fathers name available, the witnesses were John & Catherine McDermott, if he is her brother, jumping again to conclusions with no real evidence we could search for the 3 children to see if the same parents emerge. Actually it appears as Elinar McDermott, he is a widower and she has a farmer father Matthew. He was a seaman, this is Daniel Byrne now, married in Ravensdale. Have a look in this site for the various marriages after 1864 when civil registration was introduced. https://www.irishgenealogy.ie/en/
