I appreciate that the Samuel, Levi and mother Maria in 1851 are probably the wrong family but it has been puzzling me what happened to them post 1851.
I think they may have emigrated to USA New Orleans from Liverpool arriving on 19 Mar 1852 on the Kennebec. Levi Ward age 2 Samuel Ward age 5 and mother Maria Ward age 26 wife - with no husband
Added - George Ward age 23 may have arrived on 11 Mar 1850 at New Orleans on the Argo from Liverpool
