In the 1920 American census for two relatives born in Ireland I found a record in which they listed "Irish" as their mother tongue. These two folks were from the Grianan area west of Derry and St. Johnston, and were born in 1867 and 1884. There is no family legend of them speaking Irish. What are the chances that they were telling the truth in 1920 when they said their mother tongue was Irish? best, Paul Carr
