According to the website
http://www.rootsireland.ie/ Michael was born/christened on 19 October 1870 at St Mary's, Navan, Meath, Ireland.
No birth certificate was found for Michael so I'm wondering if his birth was before registration began.
He was the son of Thomas and Ellen Callaghan (formerly Melia) who were born in Navan c1848 and c1850 respectively.
Michael's siblings are;
Margaret (9 March 1874)
Christina (2 March 1876). No christening or birth can be found for this child so I'm wondering if Christina and Josephine are one and the same.
Josephine (2 March 1876).
Thomas (1877). No birth certificate found for this child.
Ellen (30 August 1879). All born in Meath.
He married Julia Gerrard on 16 January 1898 at the Catholic Chapel of Navan, Navan, Meath, Ireland. Michael died on 8 July 1952 at Mill Hill Top, Wilsden, Bradford, West Yorkshire.
Michael, his wife Julia and eldest son John Thomas appear on the 1901 Irish census. John Thomas (my great grandfather) was born on 11 November 1898 at Mill Hill Top, Wilsden, Bradford, West Yorkshire, England. I have his birth certificate.
