The Irish and the Scots have travelled back and forth since before the 5th century, it is only about 20 miles apart at Mull o Kintyre and Toberhead. They have invaded each other, helped with harvest back and forth and are quite well intermingled. If they are Presbyterians they are Scots Irish, if they are Catholic they are Irish and if they are Church of Ireland/Anglican they can be anything, as there was a time that no baptism, marriage or burial was allowed but through the Church of Ireland. However there are exceptions to everything,
Killpatrick means the church of patrick.
