There has been great discussion about Michael's actual birthday.  As you can see from the records below, the Birth Certificate lists his date of birth as October 29, 1899, however the Birth and Baptismal Certificate lists the date of birth as the 29th of September 1899, and the date of baptism as October 1, 1899.  Since the baptismal records were more accurate in Ireland at that time, the family believes that September 29th was Michael's actual birthday.  Also curious is the fact that Michael's name was changed at some point between 1901 and 1920.  On the 1901 Census of Ireland he appears as Michael O'Loughlin, and by the 1920 Census of Dorchester, he has become James McLaughlin!  Click on the images below to enlarge.
