I have searched both Irish & Scottish sites for any Mc Claid or Mc Glaid and came up with nothing
So i decided just to google the name Mc Claid and i got results

Mostly they are about a doctor in America but there was also a site called Whitepages, i think its like an American phone book. There is thousands of Mc Claid in it

Mmmmm

so now i am thinking that just maybe she came over to Ireland from America?? What do you think?
Here is the whole document, i hope it of more help to you.
Your help is very much appreciated
