Thanks for the comment about Creegan being an uncommon name in your area of Louth. My Creegan of interest is John (b. abt. 1830). We know from oral history that he emigrated in 1854 and that he had two brothers (one could have been his twin). It is also possible that his parents were both dead by the time he left Ireland. He went from Louth to Liverpool and then bought a half ticket from a family of McCann (Co. Armagh) who were going to Boston and from there to Alexandria VA to meet up with other family members. John ultimately married Kitty McCann and settled in Alexandria, raising a family of 10 children.
This is what we think MAY be true (based on possible Irish naming patterns and the known children of Kitty McCann's family):

It is believed one Creegan brother also travelled to USA and the other went to Australia. Neither brother is referred to in any existing documentation. The names William and Joseph are purely conjecture, as are Michael and Elizabeth. I shall be interested to see what you might think about this.
