John J. Tierney northern NY state

I am looking for any info on John J. Tierney son of James (aka Lawrence or Laurence) and ?? Tierney. John was born abt 1850 and died abt 1930. He married Jennie O'Brien and Ella Martin. They are all buried in St. Patrick's Cemetary in Rossie, NY. John and Ella adopted 2 children Joseph (my grandfather) and Florence. I have no info on Florence but I am interested in what I can get on her. John had 3 siblings William, James Henry and Alice Stanford. I don't have much info on these siblings but would appreciate whatever I can get.
