I have a Jane Corris born c. 1823 to John Corris and Margery Quilliam. She's with the family in the 1841 census, but not after that.

I have a Jane Corris married in Illinois in 1846 to Thomas Gill. They have a couple of children in Illinois then migrate to Dakota County, Minnesota. Jane died there in 1892 of cholera. Records give her birth as c.1823 Isle of Man.

I would very much like these Jane Corrises to be the same person. In the US records though there are no parents names given on Jane's marriage cert, death cert, or death notice in the newspaper. I cannot find an immigration record for her (1841-1846) on Ancestry.

Are there records in the IOM of emigrations for that time period that might help? Any other suggestions?
