Hi Sandra
IF Edinburgh is correct for her place of birth then Campsie is a bit far away I would think.
However, I'm not
entirely sure that it is Edinburgh.
Do you have them in 1881?
If not, here they are.

A search on the IGI shows 10 children born to this couple. One of them was Ellison

so easy to find in 1881.
I know this doesn't help you to find her place of birth.
What about the 1861/1871 censuses. Have you found them there? She was alive in 1861 as 4 of the children were born after this year. The last child (Ellison) was born in 1867
Best wishes
