Joseph - I am convinced that your family are related to mine.My gt grandfather, Henry Devlin married a Jane Bradley in Northern Ireland, and arrived in Glasgow with my grandfather, another Henry Devlin.
Jane Bradley's parents were John Bradley and Rosanna nee Birnie, these Bradleys were from Bellaghy in Northern Ireland, and John and Rosanna were married in Lavey parish in 1857.I believe that this was where your Patrick Devlin and Catherine Bradley were also married: See http://www.lmi.utvinternet.com/marrd.htmhttp://www.lmi.utvinternet.com/marrd.htm to confirm the following:
DEVLIN HENRIUS CONNOR MARIA 1852 DEVLIN JOHN KELLY THERESA 1890 DEVLIN MICHAEL HENRY ALICE 1868 DEVLIN PATRICK BRADLEY CATHERINE 1889 DEVLIN PATRICK DOWNING ANN 1871
I have been able to trace my family by finding my gt grandfather's death certificate - traceable on line at the Scotspeople GRO site - which you can find through your search engine. I found that my Gt Gt grandparents were PATRICK DEVLIN (blacksmith) and MARY MCCARTNEY- I knew they were from Co Derry, and I have been able to find out quite a lot about the family.
The names in your family are similar to those in mine.
