I am confused as to what you have and what you are seeking. Also, some of your information is contradicted by the manifest that you say you have.
First of all, I don't understand your desire to locate a transcript if you have the manifest. At best, a transcription will have the same information as the original manifest, but usually has less information and is subject to various types of transcription errors.
I am looking at the manifest pages as I write this and see at least 2 major inconsistencies with what you have written.
-- She was not traveling with a friend, Mrs. O'Donnell. This person is listed as the nearest relative or friend in the country she is coming from.
-- There is a notation on the manifest that says "accompanied by Annie Ryall who will take her to aunt in NY."
Kathleen's destination in the US is her aunt, Mrs. O'Rourke living at 762 E. 137th St., New York, NY.
