I have little to no idea of where to search because I know so little. My great-great grandmother Hannah Hennessey emigrated to the US in 1852 at the age of 6. I know plenty of her life here in the States, but no blooming idea at all of where she came from, if she came alone, was orphaned, etc. I can't find her on any passenger lists via Ancestry. I do have the International membership, and I'd surely love to find some way to learn about the Irish family she came from. Thanks in advance for any advice.
