Hello! Thank you for the replies! I have done my DNA, Ancestry.com puts me in North Munster. But I do have other Irish ancestors that were definitely in Co. Limerick (Ballylanders/Cullane) until the late 1800s also- Ireland XO has already helped me discover details about them! Different sources list different ages for Mary Carroll (which we see a lot of course- so nice to just adjust your age, right?) It says 1837 on a census record, and I just found found a babtism record that says 1835- born to John Carroll and Margaret Brennan, Baptism date Feb 23 1835 in Diocese Kildare and Leighlin. John and Margaret Carroll (born Margaret Brennen) are listed as her parents on the MIchigan Death cert, so I think this is my Mary Carroll.....
I did find a sibling, William Carroll born in 1845 to John and Margaret Carroll (b. Brennan), baptised June 1 1845 in Laois Ireland. Birth place listed as Kilfeacle. I don't see William in many other records or in Michican with Mary and trhese parents.... Maybe he died young...
Antoher sibling Patrick Carroll baptized March 25 1832 in Laois.
Another sibling John Carroll, birth listed anywere from 1832 to 1835 on US Census records.
It does appear that at least her mother Margaret (Brennan) came with her becasue I see her death date in Michigan. Not sure about the father John Carroll.
I couldn't find any parents or siblings of Thomas Delany born 1833 (or thereabouts). It is a bit confusing, there are a lot of Thomas Delanys in the records.
