I am sorry to be the persnickety 'expert' scaring off newbiews by downvoting too hastily, but I am bothered by the question Ship Passenger Manifest showing Theresa Briget Connellan as it is currently written. To preserve the original form of the question I will quote it here:
I am trying to find a ship passenger manifest listing Thersa Briget Connellan born in Clare Ireland Apr. 27, 1908. She would have sailed approx. 1923 and arrived at Ennis Island NY. The family would like to have her name added to a monument which lists the passengers who sailed from Ireland. We have found her on the Ennis website but we need the departure manifest as proof of her leaving Ireland.
So far @bgwiehle and I have made a couple of lookups and posted some comments. I would like to see a little more research effort from the person who wrote the question before going on with it. My concerns (from smaller to larger) are:
- As written the question runs afoul of the sensible suggestion to avoid writing question titles which have the names of individuals in them. (Keeping the question title about the problem rather than the person is a useful technique to avoid low-content cousin-bait.)
- Technically speaking, at what point are we in violation of the Ancestry Terms of Service when we provide lookups for other people who do not have their own accounts there? Besides, I thought it wasn't the point of G&FH.SE to be a lookup service, but instead to guide/teach others in how to do research better for themselves. How can we phrase comments to avoid the impression that we are a lookup service? (I see this has already been discussed in How to handle “look up” requests?)
- If the result of our work will be part of a physical memorial, that in and of itself becomes part of the historical record. This to me calls for a higher standard of accuracy than simply playing the "can I find things on Google faster or better than the next person" game with which I've amused myself on G&FH.SE so far. Note the big red flag word PROOF. There's a huge difference between me finding manifests about my husband's own family, where I can say to them "these are the manifests which most closely match what you have in your own family's papers, and here's how I can explain the discrepancies", or digging out a record for another experienced family historian here, versus this question, where I might be handing over a raw search result to someone who might have little to no understanding of how to properly do research, never mind the Genealogical Proof Standard or whatever equivalent standard of work you'd like to invoke.
As I said in my comment on the question, I would like to see some more input from the person who wrote the question, instead of just handing over a list of possible arrivals. As written, I don't feel it is possible to make any kind of definitive answer that a particular manifest is the person that Mark is looking for.
Editing the question to add some material from comments I wrote on ColeValleyGirl's answer and then deleted.
I appreciate her efforts to re-write the question for clarity. My difficulty with the question in both its original form and its edited one is that the question doesn't make any sense. If you have found someone on the Ellis Island website, then why not just read the manifest while you are there? What's the impediment?
If, on the other hand, the questioner has some other record that asserts that the person came through Ellis Island, I want to know what that record is and what it says. How can I judge the reliability of a piece of evidence when I don't know its provenance? How can I advise them on the best ways to cope with unreliability?
In the example in my answer, we had a handwritten family record with the arrival date and ship name on it. We don't know the date that this record was made, except that it had to be after 1930 when the Naturalization certificate was issued, because the Certificate number is also on this summary of information. We can guess at who the informant might be by the handwriting on the document. The manifest I think is ours has the same ship name, and the same arrival month, but the arrival date doesn't match. The family document must have been created three decades after the first arrival mentioned in it, and two decades after the second one. If you insist on precision, like expecting someone's birthdate to be exactly right, you aren't going to find things. This is why I wanted to know where the questioners information came from.
