A technique is to look at other names on the ship's list who were from the same locale. Of course, Yindra might have been Jindra in Czech. Is the pic I've attached the right list? She was age 63? This manifest is from 1930, but it was the only one I found in the 20s decade. It would help to have the first names so we could look them up. I did find a Katharina Jindra in 1923 and 1926.
