The Breen family from the Townland of Knockmore

I am a direct descendant of John Breen & Mary Kavanagh who had a farm in the townland of Knockmore at the begining of the 19th century. I do not know the names of all of their children but they included Thomas ( my great grandfather), Hannah and Peter ( whom I understand emigrated to USA and fought in the American Civil War). I would be delighted to hear from other descendants of that family
