Are you saying Martin and his second wife Mary Jeffreys were the parents of all the children you named? And that they were married in Ireland and at least some of those children were born there? Can you approximate a marriage date from the births of the children? I cannot find the birth of Martin born 1866 in Ireland. I was unable to find any births in the civil registration for galway with Martin Heaney as father. The surname Jeffreys is rare in Ireland. Griffiths lists only 10 of that name in the whole of Ireland in 1855.None in Galway. There were 3 entries in Mayo,all the same person- Robert Jeffreys of Pollranny ,Achill parish,co.Mayo. He was a person of some substance,as he leased over 80 acres,a hotel and ferry,as well as the petty-sessions court house. You didn't specify what religion the family was,and what occupation/status?
