Thank you Nigel for this. I've been looking at the family of John Christian and Mary Corlett as well and agree that this is probably their family. I'll be doing some more digging to be sure. They may have emigrated about the time of the Kaighins but I don't have any evidence of that yet. The Kaighins were in Birkenhead when Ebenezer was born in 1850 and then emigrated to Brooklyn, NY in 1852, but haven't seen any footprint of Christians near them until the mentioned Robert Christian in Cleveland.
