My James Trainor in Larne looks like he was a witness with a Mary Magill to the birth of a Jane Maxwell in Larne to Hugh Maxwell and Catherine Scally - quick note from the UHF. Year wasn't noted - about 1870 I might suspect - but may be wrong [a look up in the LDS may help confirm this]. Maxwells appear in the Whitewell 1911 - see Look up requests 1911 carnmoney - near my family links from Larne.
John and Susanna Maxwell COI Children: Thomas, Hugh, Bryce, James, Susan 15/9/6 Antrim. 15 years married 9 children born 6 alive 1911 Whitewell
Any link?
