Diane:

I am in search of the Parents of the following:  Eleanor O'Sullivan of County Kildare.  Here is some history:

John Lawless (1791-1871) was the son of John Lawless of Ireland. John (Jr.) was a blacksmith in County Waterford. He and his fiancee, Eleanor O'Sullivan of County Kildare, eloped to Paris, France, where they were married February 15,1815. Eleanor's parents were of Irish nobility and objected to their only daughter marrying a blacksmith. From Paris the young couple migrated to the New World and landed at Bay Fortune, P.E.I. They settled at Little Pond, King's County. John & Eleanor raised 10 children. Eleanor lived until May 14,1896 aged 104 years.

Would you be willing to help/advise of how I might be able to find out more information.  I did the  1911 Ireland Census and found an:

Eleanor O'Sullivan - Farmers Daughter

Mary Eleanor O'Sullivan - Scholar

I am uncertain of the complete definition of Irish Nobility and if perhaps Scholar would be  consider within that title in a 1911 Ireland Census. 

Thank you for you time and consideration.

All the Best!

Bill
