McCann and likewise supports the 1886 date, and the record of his first marriage in 1913 calls him James Parnell McCann.There is no possible doubt that the politician was the James Parnell McCann born in 1886, as his parents and wives are named in two different biographical dictionaries published during his own lifetime.It is possible he came to be known as James "Joseph" McCann following the early death of a younger brother named Joseph, born in 1895.
