Yes Manchester does belong in Lancashire....except when it is in Gtr. Manchester, i.e. searching Electoral Rolls on FMP.
I've searched for people I've known to have lived in Manchester, but broadened the search to 'Lancashire' and not found
them, but then have under ' Gtr. Manchester '.
These records however, I have to say, are a very welcome addition to the FMP resources. Because they are up to date (2013),
when a subject's entry does not appear after, for example 2004, they have moved on or deceased. Sadly for me I have found
death (in one case - Premature) to be the reason.
