Ireland Native
Margaret (Swieny) O'Donnell was born in Ireland.

Margaret SWEINY, daughter of Roe Sywny. [1]

Ennis Chronicle, Monday, November 29, 1790[2]

Married last Thursday, Mr. John O'Donnell of Dunmore to Miss Margaret Swieny, daughter of Mr. Roe Swieny of Moriesk, an amiable and accomplished young lady, with a handsome fortune

Their son Roe O’Donnell married Anne Roche on 19th January 1828 and they had at least 9 children, one of whom - Eliza married a police constable named Christopher Blanc from Portarlington, Co. Laois (AKA Queens) on 27th April 1862 in Killard Parish. Blanc as the name suggests is French in origin. They were amongst a large number of French Huguenot families who fled France to avoid religious persecution and settled in Portarlington. The Huguenots incidentally founded that town and it was a French speaking area. The O’Donnells and the Blancs were Protestants. After their marriage Christopher and Elizabeth (Eliza) emigrated to Brisbane, Australia and Christopher reverted to the family trade as a butcher and seems to have had a number of retail outlets in that city.[3]

Ennis Chronicle, Monday October 16, 1797[4]

Died, last Thursday. very deservedly regretted. Mrs. O'Donnell wife of John O'Donnell of Dunmore
