I did a search for E* Spiewak, and then narrowed it down to anyone born in 1930 +/- 5 years. There were two results, and only Ella was in the appropriate birthdate range for her to have signed the album.
There is a Chuna Spiewak listed at the same address as her, although his former name was Chuna Korman--perhaps a father or an uncle? No deportation information is listed for him.
A deportation date of April 19, 1942 is listed for Ella, although there is no corresponding deportation for that date under Secondary Sources, so it is unclear as of now where she went.
