Thanks for all your comments. I was taken by Moshe Davis's example of Robert. I read that Bob Dylan's hebrew name was Shabtai. (My) Samuel Servian's sister's eldest son was called Reuben, which later became Robert when he emigrated to the USA from Liverpool in 1907.  Whether he was named after Shapsei I do not know. Also equally possible, Samuel's brother Abraham/Albert named his youngest son Sidney, which may be more likely.
