Coyne family of Loughaunbeg and Spiddal

I am looking for information on  Michael Coyne of Loughaunbeg and his family.

I believe his wife's name was Connolly or Conneely before they married in 1863 and she was born in Spiddal. During the years of 1886 - 1905 they had 9 children, Martin, Mary, Ellen (my great-grandmother), Michael, John, James, Patrick, Joseph, and Edward; most of whom (possibly all) migrated to Portland Maine in the early 1900's.

Martin, the oldest child moved back to Galway, lived and died in Spiddal.  I can't seem to trace this family back any further. I would love to be able to. I have found photos of some of my great-uncles, and Mary, my great aunt on Ancestry but none of my great-grandmother, Ellen. I would also love to know more about Mary, my great-great-grandmother. Any information or a point in the right direction would be so helpful and I would be so appreciative!!
