Yes, that looks likely. Thanks. Is that a name local to the area? ('fraid I only know about Devon where we have lots of lovely Nosworthys, Widicombes, Winnecotts, Coneybeares, Comberbatches, Petherbridges, Nankivells, Endicotts, etc - all subject to infinite numbers of spelling variations and mistranscriptions . . . Lovely!)
I've found a Margaret Ann SHERRAT on the Cheshire BMD born in 1867 in Stockport. And another (also SHERRAT) born 1868 in Warrington. So either could be her I guess.
Also found on FREE BMD a Margaret Sherratt (1867 Stockport), a Margaret SKERRAT (1867 Manchester), a Margaret SKERRATT (1868 Wolstanton), a Margaret SHERATT (1869 Warrington) and a Margaret SHERRETT (1869 Salford)
So spoiled for choice. But a variant of that surname looks very likely - and it obviously is a local name.
