Hello Christy,
Sorry for the delay in replying. I've just noticed your message.
Have you done some research from the present date working back and found that you're stuck? If this is the case have you any information about the family in Tyrone that might help people give you some assistance ... the family surname would be a good start.
If you'd like a family history site which has more members able to assist you try
