Brian From my own experience of much the same thing, I suspect that the LancsBMD entries are based on year of birth, but the GRO indices are based on year of registration of the birth. In the example you give, this would fit with Martha being born at some point, probably late, in December 1875, but the birth being registered in January 1876, perhaps only a few days after she was born.
