Robert, I have this week found that my Great Aunt Agnes Roberts married a Robert Sperring and they were based in Newport, Wales before taking their family to live in the U.S.
They sailed on The Caronia from Liverpool and arrived in New York on 9th Apr. 1911. Agnes was born in Grosmont, Nr. Abergavenny on the Welsh Border. Would there be any chance your family may be connected. I would be grateful for a reply.
