Hello -- I am their great-great granddaughter. My grandfather has told me that Alexander and his two brothers (one named Robert, the other we do not know) sailed from Ireland to St. John in the 1880's. Alexander and Robert left the ship in St. John -- but they left the third unnamed brother sleeping on the ship and he ended up in Pennsylvania.
Any additional information that you could give me would be appreciated as my grandfather is very interested in his lineage and I have not been able to find anything as of yet. Thanks!!
