"Tomasz Kołodziejczak (1967-) is a Polish science fiction and fantasy writer"
A name check at Ellis Island Records does not bring up a perfect match.
Wait for Polonius3 to post on this thread. He usually has the answer to this type of question.
We are looking for any information about the name, ethnicity or meaning of her name.
Is this her maiden name or married name ?
Have you checked her marriage / death records ?
Have you checked her naturalization records ? That is, if she went to the USA.
Have you checked your mother's papers ?
If this is your mums mum then you might find grans maiden name on your mums birth certificate.
