Corrigan from Achill Island Co Mayo Ireland

G'Day to my fellow researchers.
I am tracing my Corrigan family line from Shraheens, Achill Island ,Co Mayo, Ireland.
My Great grandfather John/Sean Corrigan 1879-1955 was married twice . Firstly to a lady called Mary Kilbane 1879-1908 and had 3 boys, one of which was my grandfather Michael Corrigan 1904-1970. After Mary passed away he later married a lady called Julia Patten. They had 2 girls, Norah, who sadly died of TB at a young age and my dad's favourite Aunty , Sarah , who I think married a man called Kilcoyne.
