I wish to trace the family of a Captain Alabaster. He married the (only) daughter of Humphrey (O') Sullivan (1863-1921)and Florence Camilla Smith about 1920. Humphrey was born near Cork, son of Patrick Sullivan and Ellen Kiely. He was an officer in HM Customs & Excise. He married in Bromley in 1895. He died im Stroud (?), Gloucestershire.
