Rock family search
We are searching for verification that our John Rock was originally from County Roscommon, Boyle Parish. The 1850 U.S.A. Census lists John Rock, age 24, living in the Dixon Township of Lee County, Illinois, with his wife Mary Rock age 23. We know with certainty that this John Rock is my husband's 3rd great grandfather, and we know from subsequent Census records that he was born in Ireland. I have contacted distant cousins who say that he was born in County Roscommon in 1821, and indeed I have found a baptismal record that a John Rock was baptised 2 July 1821 in Boyle Parish, to Patrick Rock and Anna Mcniece. However, how do we know for certain? Can anyone help me with any further evidence? Another of his brothers also emigrated, named Patrick Rock born 1822 Ireland and died 1900 in Illinois, USA.
