Mitchel family

My great grandmother, Mary Mitchel Heffernan emigrated to the US in 1886 at the age of 16.  Her parents were John Mitchel (1831-1898)) & Catherine Power (1840-1911).  Mary had seven siblings--Ellen, John, Martin J., Edward Paul, James, Patrick, & Peter.  I know that Martin & Edward also emigrated to the US & lived in the Philadelphia area.  I believe that Mary's father, John died in Terryglass.  According to a 1901 census record Catherine Power Mitchel lived in Ballycormuck with her son Peter whose occupation was listed as Postman.  I have photos of John & Catherine as well as photographs of a home "Moat Villa".  I believe that their neighbors were Misses Ann & Mary Pelly.  I also have photos of the church & national school that were taken in 1960. I would be most greatful for any information about my family.
