Looking for info about Bridget Leahy's parents, Thomas & Margaret Leahy. Bridget was born in Ireland and immigrated in 1847 to Charleston, NH, then to Warren, IL, then to Darlington, WI where she met & married Michael Sweeney on 27 Nov 1860.

I can't find her with her/her parents in the 1850 or 1860 census or even a ship record. any help would be great.
