I can?t see a Patrick Bonner birth in the civil indexes in 1869/70 in Letterkenny. Nearest matches appear to be 1866 in Milford and 1873 in Glenties.
Regarding Julia?s place of birth, I suggest you search the Scottish censuses for that information. The couple appear to have been in Shettleston, Glasgow in 1911, so should be easy enough to locate her place of birth from that. (Scotlandspeople site). You should also get the details of any children born by 1911 from that census too.
