No, I don't have the passenger record for Robert R. but if he went with Thomas I would say the 1853 would be the one. The family story is that Robert came when he was about 18 and that would fit. My mother had said 1854...but you know how these stories are. My Kissacks came in 1854...and that could be a factor.
I have found Robert Radcliffes on ships, but never the right age.
Thanks, Sue, for all that great information.
