Hi Dave,
During the 1960s & early 1970s, each time "A Night To Remember," was shown on TV my dad, a former Royal and Merchant Seaman now deceased, would tell my brother and I the tale of his Uncle Jimmy being on the Titanic. We would role our eyes to the ceiling and let the moment pass without further question.
Years later, in fact just a few years ago, I was able to vindicate his claim by discovering James Brooks, Trimmer in the crew list. While I haven't absolute proof of the family connection it seems extraordinary that he would be spinning such a yarn had it not come down the family line. James would have been dad's great uncle.
Best regards,
Steve Brooks
