I am just a little bit excited! Have you checked out the new Ancestry.com Immigration Collection? Well, technically, it was an update, but boy, what an update! Look under the image in this posting to see specifics of the 66 million records that have been added.
Selfishly, though, I'm just thrilled! It's no surprise that I couldn't resist taking this for a spin -- and what do we all do in those situations? We go poking into our own roots, of course! So I thought I'd try an Irish immigrant great-grandfather of mine who's always been a challenge. There are family stories that he continued to return to Ireland on a frequent basis, but I had never been able to find any proof. So I searched on his name -- David Shields -- and limited it to fellows with this name who were born within 2 years of 1857. Ta-da! There he was in 1929 as a 70 year old returning from a trip to Ireland! I'm sure it's him because the street address given is correct. And look! There's passport info -- another clue to pursue!
The only bad news? It's inevitable that I will now spend hours playing with this new -- well, much improved -- toy! Here's hoping you find some long hidden ancestors as well!
