I have a website "County Mayo Beginnings" in which I have a section on the Irish
in South Bend.

I found an Edward Fogerty and wife Rose (Kennedy) in both the 1876 and 1880 census for
St. Joseph Church in South Bend. I don't know if this is the Edward Fogerty and
Catherine you are referring to. In the 1876 census, Edward was 49, wife Rose 48, dtr
Katie 19, Ellen 11 and Edward 9. In 1880 Edward was listed as 53, Rose Kennedy 51, Katie
19, Ann 15, Edward 14 and John 11; Two of their children Edwardus and Rosa were baptized
in the Sacred Heart Church Records (at Notre Dame) in 1866 and 1869 respectively. I
didn't come across their marriage record in my research but the South Bend
Genealogical Society would have access to searching the marriage records etc at the
archives.
Hope this helps
