Emmett O'Hare family of Pittsburgh, Allegheny Co, PA

I am searching for information about Emmett and Nellie O'Hare who moved to Pittsburgh, PA from Irwin, PA around 1915 with their two children Martha and Emmett.They built the home I currently live in and the family retained it until 1979.I know that Nellie passed away shortly after my house was built and that Emmett was a conductor on the PA Railroad and that at least part of the family may have relocated to CA in the early 1980s.I'm trying to find out some more information about Emmett's family and maybe even a few photos to round out my house's history.Anyone with any information, please get in touch with me.Thanks!
