My 2nd great grandmother was Anne Hagan Corrigan.
She was born about 1840 in Ireland.
She had been living in Tyrone. It seems that husband John Corrigan died and over the years, Anne as well as many of their 9 children headed to the Philadelphia area of PA.
Don't know much about the Hagan's that stayed in Ireland. Anne's parents were Hugh Hagan and Bridget Kelly Hagan.
Let me know if there is a connection, would love to learn more.
