Annie Kerr

That's a good big match for your mum's sister.  That's a 50% chance of 2nd cousin, once removed and about 30% for third cousin, so I think we're on the right track and that Mary was a sister to Anna.  Have a place in Ireland (County Fermanagh) is also a good start; can't go any further back as we have to find the link first in Ireland.
