Sorry, just to clarify, what does MMN mean?
I've been trying to find a Sarah Ann Robinson in the 1901 census, and the strongest possibilities seem to be these two:837 Barkerend Road (RG13/4151 fo124 p11) - Sarah A Robinson as wife, but no husband present; also an unmarried daughter Alice M Storey, age 25. GRO index suggests Alice's mother's maiden name was Redsdale. FreeBMD has the marriage of Sarah Ann Storey to Harry Robinson in 1885.27 Violet Court - in the Bowling area (RG13/4145 fo15 p21) - Sarah Ann wife of Lewis K Robinson; possible marriage in the Halifax district in 1875 of Lewis Robinson and Sarah Ann Jubb (from FreeBMD).Do any of those extra surnames ring a bell? (But do check these for yourself, and there might be other possibilities that I've missed.)
Mother's Maiden Name - can be seen in the GRO online birth index and from 1911 onwards (I think) at FreeBMD.
if you get to look at the Bowling registers themselves , they should have an address for the deceased. In several instances an infant will also have a named mother and father. Pauline
