Actually that is one piece of information I already did have thank you. I have the records. Try as I might I have not found anything on either of them after that date! Nor on the DOD for John or Johanna.
I have entertained the possibility Timothy was actually a nephew or other relation of John and Johanna who came to live with them. The other possibility was that Timothy was John's by his first marriage (except that he was younger than my G-grandfather and his brother)
The puzzling fact is that my Great Grandfather Daniel who would have been his half brother or cousin, didnt name any of his children after Timothy. There were 4 sons of Daniel - John, Cornelius, Daniel and Francis. (I am Daniel Francis, My older brothers middle name is John, my younger brothers middle name is Cornelius!) Knowing what we know about Irish naming conventions, it seems odd that one of them wouldn't be named Timothy? You can see how even 2 generations removed my mother still managed to get all of her uncles names into myself and my brothers.
