Gaps in the civil registration index?

[snuttall]

I have learnt from asylum records that my relative Jane Hargreaves died in an asylum in March 1956 in Winwick, Cheshire (Warrington registration district I believe).

However I can't seem to find any BMD index entry corresponding to that death. The archivist at the record office said something about a gap in the records but I wasn't sure if that was in relation to what they had available on site, or the actual indexes themselves? Surely there isn't a gap in civil registration especially that recently in time?

Snap Geoff-E.  And Winwick comes under Newton Registration District.

And Winwick certainly wasn't in Cheshire in 1956, as it's north of Warrington which was then in Lancs (and should still be, IMHO).  The Newton is Newton-le-Willows.
