I found Margaret / Auntie Maggie!
Margaritam McCanna born to Jacobus McCanna and Maria Kelly, baptized on 9th December 1858 at Kilronan, Co. Roscommon.
Margaret McKenna born to James McKenna and Mary Kelly, baptized on 9th December 1858 at Kilronan, Co. Roscommon.
Now I can return to the hunt for the final resting place of her mother Mary Kelly and her brother Michael.
Thanks one and all for your help!
