Thanks for the quick response. I thought I was going mad searching through the Ancestry card cat. to no avail! I have come across a few of these- it seems they batch update records and we have to wait until they get around to them. Indexing is somewhat poor on Ancestry also, so I always find using other search facilities useful (eg, familysearch)
The mother was Jane Holden, and the daughter would have been born on Oct 7th, 1884 at Queen Charlotte's hospital. She was unwed (father was James Smith). I am travelling to London after Easter and will visit the Metro. Archives, so have noted the references thank you
