Not sure I can help you, Peggysue, but maybe we can help each other going down a blind alley. The last address I have for my grandfather, Thomas Sheridan, is in Palmerston Lane, c 1 1924. His wife was Anastatia, nee Moylan and his sons were James Joseph and Patrick Joseph. As I have no other information on him,I'm always on the look out for possible relations I don't know about.
