Your 2 other posts have details of McCutcheon family and I'm not sure how or if they all connect to each other.
"my Great Grand Father was born in Tullow Co. Carlow Ireland in 1883 his name was Christopher W. McCutcheon and he has 1 brother Alexander and 2 sisters Kate louisa and Sarah, that I know of so far. Their parents were John McCutcheon (Scotish Presbyterian) and Eliza Wedekin/Wilkinton (German). They came to Ireland first to Sea Field Co. Sligo and then to Tullow Co.Carlow. Johns Mothers Name was Eliza/Ellen McCutcheon (nee ?). Died 1898 aged 92." and "record of a John McHutcheon and an Helen Ross marrying in Kirkoswald in 1834. has anyone come across any information about this couple, as i cant find any record of them after their marriage, no children, no death, not in census."
From the details you've previously posted (quoted above) John McCutcheon married Helen/Ellen Ross (c1806-1898) in Scotland in 1834. Children:
1. John McCutcheon (born c1836) m. Eliza Wedekin/Wilkinton and had: Christopher W. (1883), Alexander, Kate Louisa and Sarah.
2. Sarah (born c1841/4).
3. Alexander.
To search for church records in Ireland you need to know where the family lived (parish if not actual townland) and then check to see what records for that area survive. Unfortunately "Co. Antrim" covers too large an area and too many Presbyterian congregations to start searching.
If the information I've extracted from your posts is correct it might be possible to get more information on the family. So, some questions to see where to start looking- don't worry if you don't know all the answers yet.
1) where and when were John McCutcheon and Eliza married? what is given as John's occupation? his father's occupation?
2) where and when were John's children born?
3) have you found any of the family in 1901 and 1911 census records yet?
