I am a g-g-grandaughter of Cornelius Ardbawn however there were 3 Cornelius Callanans around the same time one born 1812 the others 1798 & 1802 same address!! The families live next-door to each other, however we are able to differentiate for the 150 yrs before that is posing a problem. We have copies of rent books with info like Cornelius(John) Cornelius (Andrew). I know from my Uncle Thomas in Ardbawn that someone from your family has contacted him, do you have direct lineage back to Ardbawn ? I am searching for the girls born to Cornelius and Ellen Mockler between 1843-1860. Their brother Michael went to St. Louis.
