I'm currently searching for my Irish ancestors and I've hit a brick wall. I've got as far back as Stewart Welsh (born in 1841 in Newtownards) who died on 25th June 1915 in Annan, Scotland. He married Mary Ann Parker (born in 1843 in Newtownards) on the 29th of December 1863. They had 6 children all born in the Newtownards area and then 1 in Annan, Dumfrieshire. As far as I can tell they moved to Scotland between 1875 and 1877, I got this information from their children's birth certificates.
Stewart Welsh's father is William John Welsh or Welch and Eliza Mogue or Magee (I cannot make out her maiden name on Stewart's wedding certificate. Mary Ann Parker's mother is Martha Boyd and her father is Joseph Boyd according to her death certificate.
I have tried searching on Ancestry (paid subscription) FamilySearch and Irish Genealogy.ie. I searched the church records for Stewart and Mary Ann on IrishGeneology.ie with no luck.
