My relative Sarah King died on the Lusitania in May 1915. On the passenger list it says she was being deported back to the UK. I would like to find out why she was being deported. I don't know exactly when she arrived in America, but she had a child Maria born in Sale, Manchester, England in 1912. The child stayed in Manchester with her grandparents Tommy and Maria King. I don't know what happened to Sarah's partner Michael Docherty (they never marrried).
Can anyone tell me where I can find out about deportations from the USA to UK in May 1915 or any other useful information. Many thanks.
