She has had this information since 2009.http://boards.ancestry.com/topics.immigration.depeng/2626.1/...
She keeps posting the same query without ever mentioning what others have now searched for at least 4 times and she has replied to them indicating that there are multiple discrepancies.
There is a conflicting set of data. She insists Mary was born in 1873, emigrated aboard the Austrian in 1883 and was, therefore, 10 years old.
The only manifest that anyone can find is the one you reference in which Mary is 18.
Either her information is incorrect or this is not her Mary. But, she keeps asking over and over.
