I've got a birth cert and marriage cert for Thomas Donnelly and I got a marraige cert for Michael Donnelly, that's where i got his fathers name from. I also found all the graves in Glasnevin. Michael's too.
The only thing I haven't got is a birth cert for Michael Donnelly.
According to the 1911 census which I think was recorded in April of that year, Michael was 40 and was orignially from Dublin city. I wrote to the GRO in Roscommon looking for his birth cert and gave an approx date for his birth, say between 1869 - 1872 and they couldn't find anything. After I got his marriage cert I wrote again with his fathers name and they still couldn't find anything. So my only hope is going to the National Library to see if I can find a baptism in one of the Churches in Dublin. Probably the Church of St Andrew on Westland Row where they got married.
I searched the following website and I couldn't find anything there either.
