Well, according to the GRO a George Bomforth's birth was registered in the June Quarter 1839, at East Retford, Nottinghamshire. In the June Quarter of 1841 a James Bomforth was born, also at East Retford, Nottinghamshire.
Both had the same mother's maiden surname : Theaker.
SO I would go with merging the Bamforth profiles INTO the Bomforth ones.
That would mean the UNKNOWN mother can now have a proper Last Name At Birth.
Are you Profile Manager for any or all of them?
